Lab created and Lab grown and synthetic are
synonymous terms. To use any of these terms, according to the FTC, the
gemstone must be identical to the natural in every way. Composition, Hardness,
and Optically. Below is an excerpt from the FTC guidelines for gemstone sales
for your reference
"(c) It is unfair or deceptive to use the word
"laboratory-grown," "laboratory-created,"
"[manufacturer name]-created," or "synthetic" with the name
of any natural stone to describe any industry product unless such industry
product has essentially the same optical, physical, and chemical properties as
the stone named." No Lab Gemstone is RARE, as the rough can be
made anytime.
