MURFREESBORO, Ark. (AP) — An 8.52 carat diamond has been found by a Colorado woman at Arkansas' Crater of Diamonds State Park at Murfreesboro. 
 
 Park officials said Friday that the gem found by Bobbie Oskarson of Longmont, Colorado, is the fifth largest diamond found since the park was established in 1972. The park does not provide an estimate of the diamond's potential value. 
 
 Park interpreter Waymon Cox said Oskarson found the gem Wednesday in the southwest corner of the 37½ acre search field and named it Esperanza Diamond for her niece's name and the Spanish word for "hope." Cox said the diamond is about three-quarters of an inch long and as big around as a standard No. 2 pencil.

 (MURFREESBORO, Ark.)--An 8.52-carat white diamond was found Wednesday (June 24) by Bobbie Oskarson of Longmont, Colorado, at Arkansas’s Crater of Diamonds State Park, according to park officials. Clear white and icicle shaped, this gem is the fifth largest diamond found by a park visitor since the state park was established at Arkansas’s diamond site in 1972. Twenty minutes into her search, she found the diamond in a couple scoops she had dug from a small mound of dirt. Oskarson was in the southwest corner of the park’s 37 ½-acre search field in an area known as the Pig Pen, aptly named because it is the muddiest part of the search area after a good rain. She named her gem the Esperanza Diamond, both her niece’s name and the Spanish word for “hope.” At this time, Oskarson plans to keep the gem. 
 
 Now in the park’s record books, this 8.52-carat diamond is topped in size only by these previous four larger diamonds found by park visitors: the white 16.37-carat Amarillo Starlight found in 1975 by W.W. Johnson of Amarillo, Texas; white 8.82-carat Star of Shreveport found in 1981 by Carroll Blankenship of Shreveport, Louisiana; white 8.66-carat Illusion Diamond found in 2011 by Beth Gilbertson of Salida, Colorado; and brown 8.61-carat Lamle Diamond found in 1978 by Betty Lamle of Hitchcock, Oklahoma. [NOTE: The largest diamond ever discovered in the U.S. was unearthed at Arkansas’s diamond site in 1924 during an early mining operation prior to becoming an Arkansas state park in 1972. Named the Uncle Sam, this white diamond with a pink cast weighed 40.23 carats. Another notable gem found at the site prior its becoming a state park was the 15.33-carat Star of Arkansas, a white diamond found in 1956 by Winifred Parker, when the site was operated by Howard Millar as a privately-operated tourist attraction.] 
 
 Park Interpreter Waymon Cox said, “Ms. Oskarson and her boyfriend Travis Dillon saw the Crater of Diamonds State Park on an Arkansas highway map while in the nearby town of Hot Springs and decided to visit the park. And what a lucky first visit it was for her!” He noted that Oskarson found the diamond on Wednesday around noon hunting in the park’s 37 ½-acre search area that is the eroded top of the eighth largest diamond-bearing deposit in the world in surface area. “It was hot and sunny at the park, but Ms. Oskarson was staying cool by searching in a tree-shaded area when she found her diamond.” Park officials recommend that visitors bring drinking water and stay in shade as much as possible when looking for diamonds during the summer. 
 
 At first she thought it might be a quartz crystal due to its elongated shape, but park staff later confirmed that she had found a diamond. Cox said, “Ms. Oskarson’s eight-and-a-half-carat diamond is absolutely stunning, sparkling with a metallic shine, and appears to be an unbroken, capsule-shaped crystal. It features smooth, curved facets, a characteristic shared by all unbroken diamonds from the Crater of Diamonds.” 
 
 He continued, “Ms. Oskarson’s diamond is about three-quarters of an inch long and as big around as a standard No. 2 pencil.” It was found very near where Carroll Blankenship found the 8.82-carat white Star of Shreveport in 1981. “Now Ms. Oskarson’s diamond is a very special part of the Crater of Diamonds State Park’s history, too.” 
 
 Oskarson’s find is the 227th diamond certified by park staff this year. Cox noted that more than 30 other diamonds have been found on the surface of the search area so far in 2015, due in part to frequent rains this spring. “Rain, plus the regular plowing of the search field by our maintenance staff, increases visitors’ chances of finding diamonds in the search area.” Regular plowing loosens the soil and brings more diamonds to the surface, and then rain erosion plays its part. “Diamonds are a bit heavy for their size, and they lack static electricity,” Cox continued, “so rainfall slides the dirt off and leaves them exposed. When the sun comes out, they sparkle.” 
 
 The search area at the Crater of Diamonds is the world’s only diamond-producing site open to the public. The park’s policy is finder-keepers. What visitors find is theirs to keep. The staff provides free identification and registration of diamonds. Park interpretive programs and exhibits explain the site’s geology and history, and offer tips on recognizing diamonds in the rough. 
 
 Over 75,000 diamonds have been unearthed here at Arkansas’s diamond site since the first diamonds found in 1906 by John Huddleston, the farmer who at that time owned the land, long before the site became an Arkansas state park in 1972. Pictures and information about notable diamond finds from the site are featured on the park’s website at: http://www.craterofdiamondsstatepark.com/history/famous-finds.aspx) 
 
 Another notable diamond from the Crater of Diamonds that has received much national attention is the 1.09-carat, D-flawless Strawn-Wagner Diamond. Discovered at the park in 1990 by Shirley Strawn of Murfreesboro, this white gem weighed 3.03 carats in the rough before being cut to perfection in 1997 by the renowned diamond firm Lazare Kaplan International of New York. The gem is the most perfect diamond ever certified in the laboratory of the American Gem Society. It is on display in a special exhibit in the Crater of Diamonds State Park visitor center. 
 
 Another gem from the Crater of Diamonds is the flawless 4.25-carat Kahn Canary diamond that was discovered in 1977. This uncut, triangular-shape gem has been on exhibit at many cities around the U.S. and overseas. It was featured in an illustrious jewelry exhibition in Antwerp, Belgium, in 1997 that included precious stones from throughout the world including the Kremlin collection, the Vatican, Cartier, and Christies. In late 1997, the Kahn Canary was featured in another prestigious exhibition at the American Museum of Natural History in New York entitled “The Nature of Diamonds.” Former First Lady Hillary Clinton borrowed the Kahn Canary from its owner, Stan Kahn of Pine Bluff, Arkansas, and wore it in a special, Arkansas-inspired ring setting designed by Henry Dunay of New York as a special way to represent Arkansas’s diamond site at the galas celebrating both of Bill Clinton’s presidential inaugurals. 
 
 Over 40 different rocks and minerals are unearthed at the Crater making it a rockhound's delight. In addition to diamonds, semi-precious gems and minerals, including amethyst, garnet, peridot, jasper, agate, calcite, barite, and quartz, are found in the park’s search area. 
 
 Crater of Diamonds State Park is on Ark. 301 at Murfreesboro. It is one of the 52 state parks administered by the State Parks Division of the Arkansas Department of Parks and Tourism.

– Crater of Diamonds State Park has lived up to its name once again, in a pretty big way. Park officials yesterday announced that the fifth largest diamond ever found by a visitor to the Murfreesboro, Arkansas, park was found on Wednesday. Bobbie Oskarson of Longmont, Colorado, uncovered an 8.52-carat white diamond that a press release describes as "clear white and icicle shaped" and "about three-quarters of an inch long and as big around as a standard No. 2 pencil." It didn't take her long: She reportedly had taken a few scoops of dirt from a small mound in a tree-shaded area of the 37.5-acre park called the Pig Pen, and the diamond surfaced 20 minutes later. The AP notes the park doesn't give an estimate of the diamond's potential value. That Oskarson was at the park was itself a bit of a chance occurrence, per Park Interpreter Waymon Cox: "Ms. Oskarson and her boyfriend ... saw the Crater of Diamonds State Park on an Arkansas highway map while in the nearby town of Hot Springs and decided to visit." She dubbed the diamond the "Esperanza Diamond"; that's both Spanish for "hope" and her niece's name. The policy at the park is finders-keepers, and Oskarson does indeed plan to keep her find, which is the 227th diamond certified by park staff in 2015. The largest diamond found there was the white 16.37-carat Amarillo Starlight unearthed by a Texan in 1975; the other three diamonds that were larger than the Esperanza were in the 8-carat range. The "Hallelujah" diamond was found there in April.
