Lab-Grown Diamonds Come Into Their Own
"Around the corner from the famous Diamond District in New York City, David
Weinstein sorts through some envelopes on his cluttered desk. All of them are full of diamonds."
"'I deal with diamonds all day long, for three decades,' says Weinstein, executive director of the International Gemological Institute, a nonprofit research institute. 'To me, diamonds aren't anything spectacular. It's hard to get me to say, 'Wow!''"
"But lately he has been impressed by certain diamonds — those created in the lab."
"'These are all laboratory-grown,' he says, unwrapping diamonds and lining them up inside a folded piece of white paper. Under a bright light, he points out how colorless they are, and how, to the naked eye, they're indistinguishable from diamonds that took millions of years to form deep within the Earth."
