A diamonds primary value is the history of it's making. People are
unfortunately always going to be paying more for a diamond which has been
digged out by hard labour than created in a lab.

Keep in mind the value of diamonds is mostly a perceptive one. I am pretty
sure if you only did synthetic diamonds it would soon fail to be valuable as
the "womans best friend"

Wild guess as to why anyone can tell the difference: Lab-grown diamonds are
more perfect than mined ones. It's probably pretty trivial to introduce
impurities to degrade the color, or change the deposition temperature in order
to create faults in the lattice. Hell, throw in a microparticle or two for
inclusions.

I'd love to know more though, anyone got a reference?

Diamond growers try their best to keep out impurities and imperfections.
Elemental impurities do add color (nitrogen=yellow, boron=blue), same as mined
diamonds, and faults and inclusions do naturally happen in the process.
However, at an atomic level, they are different than inclusions and
imperfections in mined diamonds.

As a producer, I don't see any incentive to make them imperfect on purpose,
yet still distinguishable from mined diamonds. All larger diamonds intended
for gemstones come with independent grading reports, which will still identify
it as grown regardless of presence or lack of impurities and imperfections.

While not technically correct, some of the advanced detection equipment can be
thought of like looking at growth rings on a tree. You (probably) can't
replicate the growth rings of a 200 year old tree in a 5 year old tree, yet
both are perfectly valid sources of wood (sustainability, etc. aside).

 Diamond agriculturist sample their good to keep out impurities and imperfection. 
 Elemental impurity do add color (nitrogen = jaundiced, boron = blue), same as mined 
 diamonds, and faults and inclusions do naturally find in the process. 
 However, at an atomic level, they are different than inclusions and 
 imperfections in mined diamonds. 

 As a manufacturer, I don't determine any incentive to make them imperfect on purpose, 
 so far still distinguishable from mined diamonds. All large diamonds intended 
 for gemstones come with autonomous grading reports, which will still identify 
 it as grown regardless of bearing or lack of impurities and imperfections.
