I've been one of the more interested dealers when it comes to Yellow Lab Grown Diamonds.
After all, the market for natural yellow diamonds is a very specialized one - they represent a relatively small share of the overall diamond market.
This is an example of the latest developments.
The diamond is "As Grown" - meaning it was grown using the HPHT growth methods, and it was grown this color. I think the color is indeed realistic.
I would have probably grade the diamond Intense Yellow (IGI calls it "Fancy Yellow")
If you're seeing a $0 price- we're working with the grower/cutter on the price.
Please email if you have comments or questions.
