The colored diamond market is beset by treatments and synthetics. People aren’t worried, but some think they should be. By Rob Bates, Senior Editor For a low-key business, the colored diamond market has seen a lot of action lately—though not necessarily the kind of action it would wish. In the last year, two companies—NovaDiamond in [...]
NEW YORK (Reuters) – Colored diamonds are among the rarest gems in the world, commanding thousands of dollars per carat and coveted by high-end jewelry boutiques and serious collectors.

Retired Brigadier General Carter Clarke, 77, founded The Gemesis Corporation in 1995. The company, based in Sarasota, Florida, is the first to commercially produce gem-quality synthetic diamonds grown using the High Pressure- High Temperature (HPHT) process. Martin Rapaport interviewed Clarke to get an insider view on this new facet of our industry.
Are laboratory-grown diamonds a threat to the integrity of the diamond industry? Should jewelers support the development of a market for these diamonds? Is it fair to describe these stones as cultured diamonds? What are these stones? There are two types of lab-grown diamonds — High Pressure-High Temperature (HPHT) and Chemical Vapor Deposition (CVD). The [...]

What they’re doing amounts to the beginning of the end of DeBeers’ monopoly on diamonds. And it’s likely the end of exorbitant prices on diamonds – forever. Beat the rush before the [...]

When lab-created diamonds, which have been in the works since the 1950s, appeared ready to make their debut in the market a few years ago, panic ensued. One of the most commonly voiced objections centered around whether or not these diamonds would complicate an already often-confusing shopping process for the diamond-buying public. Now, as these [...]
What are the cultured diamonds? Cultured or synthetic diamonds are real diamonds. They are made from carbon, exactly the same as natural diamonds. Currently it is possible to distinguish natural from synthetic diamonds, mainly as a result of different types of inclusions, but at some time in the future it may be possible to create [...]
Diamond was discovered to be carbon in 1796, and it took more than 150 years from that time until a method of diamond synthesis was invented. The secret was pursued by many scientists but not unlocked until the 1950s, when diamond was synthesized almost simultaneously by Swedish and American researchers. Pressures of over 55,000 atmospheres [...]
