'Finest' is a judgement call, and you are the judge. Lab-created diamonds can be custom-ordered, based on the source of the carbon. You can also specify a colour of diamond that you want. Any lab-created diamond will always be a lab-created diamond, and its competitor won't be another lab-created diamond, but will be a natural diamond.
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.
Lab created diamonds, or synthetic diamonds, are created by the crystallization of pure carbon. The crystallization takes a long time, so the process is very difficult.
Yes.
Yes. A certified gemologist, however, will always be able to determine that the diamond is a lab-created diamond. It will always have a lower monetary value than a comparable natural diamond.
A mineral.
The mineral chalcanthite is composed of hydrous copper sulfate. It is translucent and a rich blue in color. Chalcanthite has a hardness of 2.5. The oxidation of copper sulfides is what causes it to form in nature.
