What is the best cultured diamond?
'Best' is a bit of a relative term. Cultured, or lab grown diamonds, are available in multiple colors from multiple labs. I would note that currently very few *white* lab grown diamonds are available. D.NEA has made whites up to one carat and Apollo Diamonds has offered some up to 1/3 carat. Of the cultured yellow diamonds, the major sellers are Gemesis, D.NEA (was Adia), Takara, New Age Diamonds and Chatham. Takara's yellow diamonds seem to be the most consistently 'pure yellow', rather than the more common orange-yellow from the other labs. D.NEA has the largest selection of blue diamonds. Pink diamonds are available at TakaraDiamonds.com and a few other sites like DiamondsCultured.com (made by Chatham). I'll add some links to the various sites and you can research from there, as best is really partially dependent on what color you like and what type of cut you want. Diamond Culture, a new supplier as of October 2009 has a large selection of IGI certified yellow, pink and lime diamonds, all cut in Antwerp. Created-Diamonds.com is an online retailer of cultured diamonds produced by different labs.
Who make lab grown diamonds?
There are currently only a handful of labs that make lab grown *gem* quality diamonds. Gemesis and Apollo are two.If you are asking about lab grown diamonds that are of industrial quality (small, not pretty pieces) then there are lots including GE, Sumitomo and DeBeers (E6).I've attached links to a grower and a seller of lab grown diamonds for jewelry below.
Which is worth more a yellow diamond or a white diamond?
The color scale for white diamonds runs from D to Z. On one end of the spectrum you have completely white without any traces of yellow and on the other end, a diamond fully saturated with yellow and no traces of whiteness. Due to the fact that they are quite common, they are actually quite affordable.
