Best will depend on what you are looking for. There are only a couple companies that offer lab diamonds, so that will help narrow your selection. Apollo grows diamonds using CVD technology and offers whites up to 1/3ct. D.NEA grows yellow diamond up to 2ct, blue up to 1.25ct, and white diamond up to 1ct using HPHT. Chatham grows yellow and blue up to 1/2ct using HPHT. Gemesis grows yellow up to three carats using HPHT.
The best type of synthetic diamond would most likely be Cubic Zircona, a popular fake jewel that is much cheaper than diamond and unlike other fake jewels it will not change color or become tinted by an outside source for very extended periods of time.
Its a simulated diamond. Or lab created.

'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.
The answer you want is based on what you consider 'best': clarity, colour, cut or carat weight. Any lab-created diamond is made from carbon and is a real, lab-created diamond. Another answer may be: the best one is the one that you can afford.
Gemesis is a company that grows yellow diamonds. These are known as synthetic, lab created, lab grown or cultured diamonds. Synthetic diamonds are real diamonds and also produced by D.NEA, Apollo and Chatham.
A lab diamond is a diamond that is created in a lab under very controlled circumstances that mimic the environment in the earth's mantle. Lab diamonds and mined diamonds are identical. The only difference is their provenance.

Yes, a lab-created diamond will test as a diamond. Lab-grown diamonds have the same physical, chemical, and optical properties as natural diamonds. As a result, standard diamond testers will typically identify them as real diamonds. However, advanced gemological equipment may be needed to distinguish lab-grown diamonds from natural ones.
The differences between natural diamonds and lab-created diamonds are best determined by a trained and certified gemologist. even if it is damaged and has a rough edge. If the diamond is a raw diamond and your query is whether or not the stone is a diamond or not, the field test for diamond is hardness. A diamond rock will scratch everything.
