The Gemological Institute of America also sent state-of-the-art screening instruments to jewelers and groups to help them detect synthetics and diamond simulates. These instruments, DiamondSure and DiamondView, are manufactured by the Diamond Trading Co. -- part of the De Beers group of companies.

In the most drastic move so far, the Israel Diamond Exchange (IDE) banned the trade of synthetic diamonds in April 2004. "There is no doubt that we must take a firm stand against synthetic diamonds," Shmuel Schnitzer, the president of IDE, said in a statement. "These are imitations, and must not be handled by members of the legitimate trade."

But, at this stage, the main industry debate over lab-made diamonds is a semantic one. Hellier, the president of Gemesis, doesn't like to call his company's product "synthetic." The industry, though, takes umbrage at the "cultured diamonds" term used by Gemesis and Apollo. As Jerry Ehrenwald from the IGI says, "When they culture a pearl, they put a seed in the oyster, and the oyster continues to secrete the nacre. It's quite a natural process. With synthetic diamonds, there is nothing natural about stone." (A German court has banned the use of the "cultured diamond" label.)

Gemesis and Apollo also want their gems to be classified by the GIA and IGI. Hellier from Gemesis says, "We think that confusing these man-made diamonds with real diamonds will cheapen or devalue real diamonds. We want them to be distinct products."

It sounds like both groups want the same thing: To keep lab-made diamonds distinct from natural ones. But to the gem-makers, that means classification and recognition. To the natural diamond industry, it means something else entirely.

Carson Glover, a spokesman for the public relations arm of the De Beers' Diamond Trading Co., dismisses claims that the natural diamond industry has anything to worry about. "Synthetics have not eaten into natural diamonds at all. These are two very different products. Diamonds are a gift of love, used to symbolize relationships, celebrate milestones -- anniversaries, the birth of a child, etc. Synthetics are not the real thing. They have amazing capabilities from an industrial standpoint, but they don't have a retail presence yet. Nine out of ten women want the real thing."

But 2004 was the first year that Gemesis' cultured diamonds were even available to the consumer market. Nine out of ten women probably have no idea they even exist. But as Apollo readies its white diamonds for market as well, that all may change quickly.

Most of the jewelers who do stock the lab-made diamonds often wax enthusiastic about their beauty, bright colors and affordability. Very few jewelers bring up social or environmental concerns as justification for stocking the gems. Fred Schrode, the owner of Schrode Jewelers in Florida, concedes that some of his customers "have definite thoughts about conflict-free stones." These customers tend to be younger, he says. However, Schrode doesn't like to get into the moral and social implications of buying a diamond. "I think that when you start mentioning 'conflict-free' to a customer, you open Pandora's box. But if you're asked by a customer about conflict-free stones, you can tell them, 'These are OK; they're grown right here in Sarasota.'"

Others, though, have no problem pitching directly to the socially aware. "My customers appreciate these synthetic stones for the ecological and social values that are embedded in them," says Matthew White, the founder of greenKarat jewelry, which sells only synthetic diamonds. "We're looking toward to a time when, instead of being apologetic about wearing a synthetic stone, those who wear the natural stones will be draped in shame."
