Dense Media Separation (DMS)
A process by which minerals are separated by utilizing each minerals unique specific gravity. Specific gravity is a relative measurement between the weight of a mineral and water. Some minerals are light and float, while others are heavy and sink. DMS takes advantage of the differences in specific gravity between various minerals as a means to separate one from another.
A tabular body of igneous rock that cuts across the structure of adjacent rocks.
Diamonds are generally either eclogitic or peridotitic. Eclogitic diamonds are found crystalized in ecologitic source rocks. Eclogites are essentially biminerallic rocks composed of pyrope-almandine garnet and omphacitic clinopyroxene.

The principle ore of titanium. A kimberlite indicator mineral.
Indicator Mineral Train
The area where kimberlite indicator minerals are concentrated is variously described as indicator mineral “train”, “fan”, “dispersion”, or “anomaly”. The “train” was created by glacial ice which carried surface material and dispersed over vast areas. Kimberlites are soft and tend to weather more readily than “older” country rocks. As a result, any kimberlite that lay in the path of a glacier was scoured out, incorporated into the glacial drift and dispersed across the landscape. Kimberlite indicator minerals were similarly dispersed through the same process.

“Piqued 1” Clarity term used by most countries other than the U.S. It’s equivalent in American Terms is I1. I1 Meaning inclusions can be seen by the naked eye.
“Piqued 2” Clarity term used by most countries other than the U.S. It’s equivalent in American Terms is I2. I2 Meaning larger inclusions can be seen by the naked eye.
“Piqued 3” Clarity term used by most countries other than the U.S. It’s equivalent in American Terms is I3. I3 Meaning inclusions are incredibly visible to the naked eye. One step lower and you would have “custom jewelry”
The paper used to wrap diamonds. Usually for single stones. It has an uncanny way of securing the solitaire diamond in place.
Usually Pave, Paved, and MicroPave engagement rings refers to the smaller diamonds that are set along side the band or next to the center or main diamonds. Usually with a carat weight of .2. Give or take a .05. Of course the size can vary.
The company that perfected the high pressure color change in diamonds. Where Enhanced diamonds have glass and various other tools to mask and sharpen the look of diamonds, they can not change the color. Pegasus Overseas changed all that by allowing a person to actually change a drastically yellow diamond into a perfect D colored perfect white diamond. Only sophisticated labs such as De-Beers, GIA, EGL and so forth can actually tell the difference using highly technical machinery.
Nothing is absolutely perfect! If you look hard enough you will find imperfections in a stone. Only you might need a highly magnified lens to see it. However in typical standards, Perfect is described as the color D and clarity of FL. Take a look at Flawless versus Internally Flawless Clarity Grading, as these two diamond grades get interchanged quite often.
The ability of some diamonds, minerals or gems to actually keep emitting light for a period of time after being exposed to sun light , normal light, ultra violet light or any other source. It’s usually a glowing effect after the light source has been removed. Sometimes referred to as Diamond Fluorescence.
One of the rarest colors and often very desirable color of diamond. VERY Expensive.
Tiny inclusions in a gem or diamond.
Usually referred to as a diamond mine.
Weight equally 100th of a carat. So a 1ct diamond would equal 100 points, and a half carat diamond would be 50 points, and so forth. See Diamond Carat Weight.
Usually faint lines left by careless or accidental polishing. Also could be lines that are just naturally occurring in the diamond itself. Learn more about Diamond Polish. It makes a real difference in a diamond’s overall beauty.
A mark on a diamond resulting from getting the diamond too hot when polishing it. Usually results in cloudiness.
A diamond substitute very often found in watches. It’s used for it’s remarkable clarity and colorless appearance.
The monthly newsletter invented by Martin Rapaport that is used by the entire diamond industry as a set standard for diamond prices. Another words if the Rapaport says a 1.3ct, G, SI1 round diamond is worth $1000 a carat than you would times 1.3 by 1000 and you would get $1300. This is what Rapaport suggests the selling price usually is. However not everyone follows it.
Retail prices, the kind you find in a lot of websites and local jewelry stores in your nearby mall all markup from the Rapaport price. At times usually 2 times the suggested price of Rapaport. So the $1300 diamond mentioned above could and usually would cost you about $2000 to $2600 in a jewelry store. Simply put Retail is the markup of Rapaport. This is how sales are possible.
The person who’s responsibility is to put, or set, the diamond into the pegs or mount of a ring.
A machine that sorts rough diamonds by size.
SI1 – Slightly Included
The SI1 Clarity term used for diamonds that should NOT show any inclusions visible to the naked eye. However under 10x magnification inclusions will be very visible.
Usually means a ring or other piece of jewelry that has only 1 major diamond mounted in the settings. Usually referred to as an engagement ring. Make note that a solitaire is a term used for defining an engagement band.
If you see a diamond with this clarity than you’re dealing with a diamond that’s absolutely junk. It’s the step below I3. Usually costume jewelry would fall into this category. Only custom jewelry is probably nicer to look at.
Usually one of the most un-talked about properties of a diamond. When in fact it usually is one of the most important. Diamond Symmetry is just as it says, and refers to the equal-ness of all sides of a diamond. The more symmetrical the more light can pass back up through the diamond and give it it’s sparkle or fire.
Diamonds that have been created in a lab. Make note that Synthetic diamonds are in fact VERY REAL diamonds. It’s a complicated process, but the diamond is actually grown in a lab using extreme pressure that mimics the natural forces of nature. However instead of waiting for millions of years for the carbon to turn into a diamond it takes about 3 days to a week in a lab. Usually Synthetic diamonds are much cheaper, and have absolute perfect clarity. De Beers, in a panic, has devised a machine that can tell the difference between good old earth made diamonds, and man made diamonds keeping the value and integrity of diamonds intact. The technology for the synthetic diamond is so good that very few people can see any difference. It does take a machine.
The very top and largest facet on a diamond.
A tool used to hold a diamond while it’s being polished.
The diamonds ability to emit light when heated.
The process of enhancing the color of a diamond or clarity enhancing a diamond outside of it’s normal process of cutting and polishing. Usually done by high pressure to change the color, or by drilling and injecting a glass like material into a diamond to change it’s clarity or appearance. Both are very popular, both are NOT illegal, both designed to enhance the beauty of the diamond.
VS1, VS2, Very slightly included
VVS1, VVS2, Very, Very slightly included
The clarity value of a diamond that’s almost near perfect in clarity. Very Very refers to that you can barely see the inclusions even using a 10x magnified lens, and you certainly can not see it with your naked eyes.
Uchunguzi wa kijiografia unaofanywa hewani kwa kutumia magnetometer. Kimberlite ni mwamba wa kimberlite, ambao una mchanganyiko wa biotite, phlogopite, na melilite, pamoja na olivine, calcite, na clinopyroxene. Almasi ambazo zimesafishwa na kubaki katika matope, matope, na mchanga uliosalia na maji yanayotiririka katika bonde la mto au delta. "Kifaa cha kijiolojia, kijiolojia, au kijiolojia, ambacho ni tofauti na mazingira ya jumla, na ambacho kinaweza kuwa kiashiria cha eneo la ""matarajio ya uwezekano wa kuchunguza almasi.""" Katika kipindi cha kabla ya Precambrian (mwaka wa 2500 hivi). Kiasi cha kazi maalum na sheria ya madini ya almasi, ambayo lazima kufanyika kila mwaka ili kuhifadhi udhibiti wa kisheria wa madai ya madini. Jiwe lililofanyizwa na vipande vyenye pembe kubwa sana. Inaweza kuwa sedimentary au kuundwa na crushing au kusaga kando makosa. Sampuli kubwa inayojumuisha mamia ya tani ambayo kisha hutengenezwa ili kuamua darasa. Kiwango cha kupima uzito wa almasi. Kiungo kisicho cha chuma, kinapatikana kwa uhuru katika asili katika aina tatu za allotropic: amorphous, graphite, na almasi. Utaratibu ambao hutumia kusaga kwa uchovu, kutenganisha kioevu kizito na kumeng'enya kabisa kwa mwamba kwa kuifanya iwe na suluhisho la msingi sana kwa joto la juu (soda ya caustic). Katika hatua ya mwisho, karibu madini yote yanayofanyiza kimberlite hufanywa yaweze kuyeyuka isipokuwa almasi. Kisha mabaki hayo huchunguzwa kwa darubini ili kutambua na kupata almasi hizo. Madini ya kikundi cha spinel. Kanuni ya madini ya chromium. Kimberlite ni madini ya kimberlite. Sehemu ya ardhi ya madini inayomilikiwa chini ya sheria za shirikisho au za mitaa na mwombaji mmoja au chama, kwa sababu ya eneo moja na rekodi moja. Sehemu ya mviringo ya mwamba, kawaida karibu inchi katika kipenyo, kuletwa juu na diamond kuchimba visima kwa ajili ya uchunguzi wa kijiolojia na au uchambuzi wa maabara. Kimberlite nyenzo kupatikana karibu juu ya mabomba; kuhifadhiwa tu katika amana ya msingi ambayo wamekuwa chini ya kidogo au hakuna mmomonyoko tangu en-kuwekwa yao. Sehemu ya tabaka la dunia ambayo imekuwa imara kwa kipindi kirefu cha muda wa kijiolojia. Kimberlites nyingi za almasi ulimwenguni pote zinahusianishwa na cratons za Archean. Almasi ni madini magumu zaidi yanayojulikana, na yanafanyizwa na kaboni safi. Diamond Stability Field (DSF) ni eneo la ndani ya dunia kati ya makazi ya dunia na ya ndani ya dunia, katika kina cha kati ya 150 na 200 km. Hapa ndipo hali hususa za shinikizo na halijoto zinapofaa kwa ukuzi na uhifadhi wa almasi. Kimberlite iliyomo ndani ya sub-volcanic <unk>diatreme<unk> yenye umbo la karoti yenye umbo la karoti karibu kilomita moja chini ya uso wa dunia. Density Media Separation (DMS) ni mchakato wa kutenganisha madini kwa kutumia kila madini ya pekee ya uzito maalum. Mwili wa mtu huathiriwa na uzito wa madini na maji. Baadhi ya madini ni mepesi na huelea, ilhali mengine ni mazito na huyeyuka. DMS hutumia tofauti za uzito wa kipekee kati ya madini mbalimbali kama njia ya kutenganisha moja kutoka kwa nyingine. Mwili wa meza wa mwamba wa igneous ambao hupunguza muundo wa miamba iliyo karibu. Kwa kawaida almasi huwa na umbo la eclogitic au peridotitic. Almasi za eklogiti hupatikana zikiwa zimefanyizwa kuwa fuwele katika miamba ya chanzo cha eklogiti. Eclogites ni kimsingi miamba biminerallic iliyoundwa na pyrope-almandine garnet na omphacitic clinopyroxene. Mbinu ya uchunguzi wa kijiografia ambayo hupima mali za umeme za mwamba. Mwamba wenye matundu ya mchanga na mchanga. Maji yaliyokuwa yameyuka kutokana na barafu au barafu iliyokuwa ikirudi nyuma. Kazi inayohusika katika kutafuta madini ya madini. Inaweza kujumuisha upelelezi wa kijiolojia, kwa mfano Utafiti wa mbali, photogeology, geophysical na geochemical mbinu, na wote juu na chini ya ardhi uchunguzi. Mvunjiko au eneo la mivunjiko katika tabaka la Dunia, iliyoonyeshwa na uhamisho wa jamaa na kutoendelea kwa tabaka au tabaka la mwamba. Mvunjiko mkubwa, kuvunjika, au kuvunjika katika miamba. Vipande vya mwamba au madini ambayo yametenganishwa na kubwa, katika eneo, mwili wa madini na nguvu za asili. Ramani ya sifa za kijiokemia za mwamba. Sayansi inayohusika na utafiti wa Dunia, miamba ambayo imeundwa, na mabadiliko ambayo imepitia au inapitia. Upimaji wa miamba tofauti ya kimwili kama vile magnetic susceptibility, conductivity na wiani kutumia vifaa maalumu ya kupima na kompyuta. Utafiti wa eneo ambalo mali za kijiografia na mahusiano ya kipekee kwa eneo hilo ni ramani na moja au zaidi ya mbinu za kijiografia. Kimetaboliki ni muhimu katika utafiti wa almasi kwa sababu kimberlite mara nyingi ina alama za kipekee za kijiografia ambazo ni za kipekee au za kipekee ikilinganishwa na zile za miamba inayozunguka. Sediment ambayo ni ama katika usafiri katika glaciers au deposited na glaciers. Mwamba coarseograined ambayo bendi tajiri katika vifaa granular kubadilishana na bendi ya hasa metamorphic mwamba. Rangi nyepesi, coarse-grained, igneous mwamba linajumuisha quartz, alkali feldspar, micas na madini mengine kuhusishwa. Katika utafutaji wa almasi, idadi ya karati katika kitengo cha kimwili cha madini, kwa kawaida huonyeshwa katika karati kwa tani. Vipimo vya uwanja wa mvuto katika mfululizo wa maeneo tofauti. Lengo la uchunguzi huo ni kuhusisha tofauti na tofauti katika usambazaji wa wiani na kwa hiyo aina ya mwamba. Madini ya mwamba sedimentary, ya uzito wa juu maalum. Kuondoa maji mazito: Kuondoa vipande vya madini kwa kuruhusu kuhamia au kuelea juu ya kioevu cha wiani wa kati. Mwili wa mwamba unaotumika kama mwenyeji kwa miamba mingine au kwa amana za madini. Jina la cheo la jumla linalotumiwa kwa uvamizi mdogo kama vile milango na miamba, na kwa miamba inayowafanyiza. Miamba ya hypabyssal ni ile ambayo imeinuka kutoka kwa kina kama magma lakini imezingatiwa hasa kama uvamizi mdogo kama vile dikes na sills kabla ya kufikia uso. Imefanyizwa kwa kuimarika kwa nyenzo moto inayoweza kusonga inayoitwa magma. Kanuni ya madini ya titani. Kimberlite ni madini ya kimberlite. Kiashiria Madini Treni Eneo ambapo kimberlite kiashiria madini ni umakini ni mbalimbali ilivyoelezwa kama kiashiria madini <unk>treni<unk>, <unk>fan<unk>, <unk>usambazaji<unk>, au <unk>anomaly<unk>. "Gari-moshi" hilo lilitengenezwa na barafu ya barafu ambayo ilibeba vitu vya uso na kutawanyika katika maeneo makubwa. Kimberlites ni laini na huwa na hali ya hewa kwa urahisi zaidi kuliko miamba ya nchi "ya zamani". Kama matokeo, kimberlite yoyote iliyokuwa katika njia ya barafu ilichimbuliwa, ikaingizwa katika mtiririko wa barafu na kutawanyika katika mazingira. Madini ya kiashiria ya kimberlite pia yalitenganishwa kupitia mchakato huo huo. Magma ya magma hutoka ndani ya ardhi na hupita katika maeneo yenye almasi zilizopatikana katika miamba ya mantle. Kimberlitic Kiashiria Madini Almasi, Garnets, na madini mengine kadhaa ambayo ni ya kipekee kwa miamba kimberlitic. Jina la kikundi kwa ajili ya rangi nyeusi hypabyssal au extrusive miamba tajiri katika potasiamu na magnesiamu. Jina la kikundi linalotumiwa kwa miamba ya mwamba yenye rangi nyeusi ambayo madini meusi hutokea; wakati mwingine ina almasi. Kiasi cha mawe ya mchanga (kila aina ya mchanga) ya anhedral (kila aina ya mchanga) na matrix ya fine-grained. "Macromolecule ni ""micromolecule"" ambayo ni diamond yenye ukubwa wa zaidi ya 0.25mm, ambayo ni muhimu kwa ajili ya utengenezaji wa diamond." Almasi zenye ukubwa wa chini ya 0.5mm huitwa'microdiamonds'. Jiwe lililiyeyuka linalopatikana kiasili. Uchunguzi wa kijiografia unaopima kiwango cha uwanja wa sumaku wa mwamba. Eneo la Dunia chini ya tabaka na juu ya kiini. Mantiki imegawanywa katika mantiki ya juu na mantiki ya chini, na eneo la mpito katikati. Inajumuisha miamba yote ambayo imeundwa katika hali ngumu kwa kujibu mabadiliko ya joto, shinikizo, na mazingira ya kemikali, ambayo hufanyika kwa ujumla, chini ya uso wa Dunia. Mkusanyiko wa kimberlite ya tani 100 hadi 100 ni hatua ya kwanza ya kuanzisha mgodi wa almasi. Kiungo au kiungo cha kemikali kilichoundwa kiasili ambacho kina safu maalum ya kemikali, na kwa kawaida kina fomu ya kioo ya tabia. Madini ya rangi ya kijani-kibichi, kijani-kibichi, au kahawia. Inachukuliwa kuwa madini ya kiashiria ya Kimberlite. Bedrock au strata protruding kupitia overlying cover detritus na udongo kuwa wazi katika uso. Inaashiria nyenzo ya asili yoyote, iliyounganishwa au isiyounganishwa, ambayo inashughulikia amana ya vifaa muhimu, madini, au makaa ya mawe. "Pickled 1""Ufafanuzi wa neno ""Ufafanuzi"" hutumiwa na nchi nyingi isipokuwa Marekani." I1 Inamaanisha inclusions inaweza kuonekana kwa jicho tupu. "Picture 2"" ni neno la uwazi linalotumiwa na nchi nyingi isipokuwa Marekani." I2 Inamaanisha inclusions kubwa inaweza kuonekana kwa jicho la kawaida. "Picture 3"" ni neno la uwazi linalotumiwa na nchi nyingi isipokuwa Marekani." I3 Inamaanisha inclusions ni incredibly kuonekana kwa jicho uchi. Hatua moja chini na ungekuwa na "vito vya desturi" karatasi kutumika kufunga almasi. Kwa kawaida kwa mawe moja. Ina njia ya ajabu ya kulinda almasi ya solitaire mahali pake. Kwa kawaida, pete za uchumba za Pave, Paved, na Micropave zinarejelea almasi ndogo ambazo zimewekwa kando ya bendi au karibu na almasi za kati au kuu. Kwa kawaida, uzito wa karati ni 0.2. Pata au chukua 0.05. Bila shaka ukubwa waweza kutofautiana. Kampuni hiyo iliboresha mbinu ya kubadili rangi ya almasi kwa kutumia shinikizo kubwa. Kwa kuwa almasi zilizoboreshwa zina kioo na vifaa vingine mbalimbali vya kuficha na kuimarisha sura ya almasi, haziwezi kubadilisha rangi. Pegasus Overseas ilibadilisha yote hayo kwa kuruhusu mtu kubadilisha almasi ya manjano kabisa kuwa almasi nyeupe kamilifu ya rangi ya D. Ni maabara ya hali ya juu tu kama vile De Beers, GIA, EGL na kadhalika ambayo inaweza kweli kusema tofauti kwa kutumia mashine za kiufundi sana. Hakuna kitu kilicho kamili kabisa! Ukitazama kwa makini utapata kasoro katika jiwe. Lakini huenda ukahitaji lensi yenye ukubwa mkubwa ili uone. Hata hivyo katika viwango vya kawaida, Perfect inaelezwa kama rangi D na uwazi wa FL. Angalia Flawless dhidi ya Ndani Flawless Clarity Grading, kama hizi mbili diamond madarasa kupata kubadilishana mara nyingi sana. Uwezo wa almasi, madini au vito fulani kuendelea kutoa mwanga kwa muda baada ya kufunuliwa na mwanga wa jua, mwanga wa kawaida, mwanga wa ultraviolet au chanzo kingine chochote. Ni kawaida athari glowing baada ya chanzo cha mwanga imekuwa kuondolewa. Nyakati nyingine huitwa Fluorescence ya Almasi. Ni moja ya rangi za kawaida na mara nyingi rangi inayotamaniwa sana ya almasi. Gharama kubwa sana. Vipande vidogo-vidogo katika jiwe la thamani au almasi. Kwa kawaida huitwa mgodi wa almasi. Uzito wa karati moja ni sawa na karati moja ya karati 100. Kwa mfano, almasi ya carat moja inaweza kuwa na thamani ya 100 na almasi ya nusu carat inaweza kuwa na thamani ya 50 na hivyo kuendelea. Ona Uzito wa Karati ya Almasi. Kwa kawaida mistari dhaifu inayobaki kwa sababu ya kupaka rangi bila kujali au kwa aksidenti. Pia kunaweza kuwa na mistari ambayo hutokea kwa kawaida katika almasi yenyewe. Jifunze zaidi kuhusu Diamond Polish. Hilo hufanya tofauti kubwa katika uzuri wa jumla wa almasi. Ishara kwenye almasi inayotokana na kupata almasi moto sana wakati wa kuifuta. Kwa kawaida husababisha ukungu. Mabadiliko ya almasi ambayo hupatikana mara nyingi sana katika saa. Inatumiwa kwa sababu ya uwazi wake wa ajabu na muonekano usio na rangi. "Mwezi huu, gazeti la habari la ""The Diamond Times"" linatumia ripoti ya Martin Rapoport, mwandishi wa habari wa kimataifa, kuelezea jinsi biashara ya almasi inavyotumia ""mfano wa thamani ya almasi.""" Kwa mfano, Rapoport inasema kwamba almasi ya 1.3 carat, G, SI1 inastahili $ 1,000 kwa carat, na mara 1.3 kwa 1000, unapata $ 1300. Hii ni nini Rapaport inapendekeza bei ya kuuza kwa kawaida ni. Hata hivyo si kila mtu anayefuata kanuni hiyo. Kwa mfano, bei ya rejareja ya bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa za bidhaa. Kwa kawaida, mara mbili ya bei ya Rapoport. Kwa hiyo, almasi ya $ 1,300 iliyotajwa hapo juu inaweza na kwa kawaida ingekugharimu karibu $ 2,000 hadi $ 2,600 katika duka la vito. Kwa ufupi, rejareja ni alama ya Rapaport. Hivyo ndivyo mauzo yanavyowezekana. Mtu ambaye ni wajibu ni kuweka, au kuweka, almasi katika pigs au mlima wa pete. Mashine inayotenganisha almasi zisizo na rangi kulingana na ukubwa. SI1 (Slightly Included) ni jina la kipekee la diamond ambalo linatumiwa kwa ajili ya diamond ambazo hazipaswi kuonyesha inclusions yoyote inayoonekana kwa jicho la kawaida. Hata hivyo, chini ya 10x magnification inclusions itakuwa dhahiri sana. Kwa kawaida, pete au kipande kingine cha vito kina almasi moja tu kubwa iliyowekwa kwenye mipangilio. Kwa kawaida huitwa pete ya uchumba. Kumbuka kwamba solitaire ni neno linalotumiwa kufafanua bendi ya uchumba. Kama unaona almasi na uwazi huu kuliko wewe ni kushughulika na almasi kwamba ni kabisa taka. Ni hatua chini ya I3. Kwa kawaida vito vya mavazi vingeingia katika jamii hiyo. Vito vya kawaida ni bora kuangalia. Kwa kawaida moja ya mali za almasi ambazo hazizungumzwi sana. Wakati kwa kweli ni kawaida moja ya muhimu zaidi. Diamond Symmetry ni kama inavyosemwa, na inahusu usawa wa pande zote za almasi. Kadiri ilivyo sawa ndivyo nuru zaidi inavyoweza kupita kupitia almasi na kuipa kung'aa au moto. Almasi zilizotengenezwa katika maabara. Kumbuka kwamba almasi za Synthetic kwa kweli ni almasi za KWELI KWELI. Ni mchakato mgumu, lakini almasi kwa kweli hukua katika maabara kwa kutumia shinikizo kubwa ambalo huiga nguvu za asili za asili. Hata hivyo, badala ya kusubiri kwa mamilioni ya miaka kwa ajili ya kaboni kugeuka katika almasi inachukua siku tatu hadi wiki moja katika maabara. Kwa kawaida almasi za synthetic ni za bei nafuu zaidi, na zina usafi kamilifu kabisa. De Beers, katika hofu, amebuni mashine ambayo inaweza kusema tofauti kati ya dhahabu nzuri ya zamani ya ardhi na dhahabu ya binadamu, na kuweka thamani na uadilifu wa almasi. Teknolojia ya almasi ya synthetic ni nzuri sana kwamba watu wachache sana wanaweza kuona tofauti yoyote. Inahitaji mashine. Sehemu ya juu na kubwa zaidi kwenye almasi. Chombo kinachotumiwa kushikilia almasi inapopakwa rangi. Kiasi cha almasi ni uwezo wa kutoa mwanga wakati inapopashwa joto. Mchakato wa kuongeza rangi ya almasi au uwazi kuongeza almasi nje ya mchakato wake wa kawaida wa kukata na polishing. Kwa kawaida hufanywa kwa shinikizo kubwa ili kubadilisha rangi, au kwa kuchimba na kuingiza kioo kama nyenzo katika almasi ili kubadilisha uwazi au muonekano wake. Vyote viwili ni maarufu sana, vyote viwili si haramu, vyote viwili vimetengenezwa ili kuongeza uzuri wa almasi. VVS1, VVS2, VVS1, VVS2, VVS2, VVS2, VVS2, VVS2, VVS2, VVS2, VVS2, VVS2, VVS2, VVS2, VVS2, VVS2, VVS2, VVS2, VVS2, VVS2, VVS2, VVS2, VVS2, VVS2, VVS2, VVS2, VVS2. Kwa kweli, ni vigumu kuona inclusions hata kwa kutumia lensi ya 10x, na kwa hakika huwezi kuona kwa macho yako.
