What it is
The FTC-accepted term for a lab-grown stone with the same chemistry as the natural one. 'Created' never describes a simulant.
Lab-grown and simulants: Lab-grown stones have the same chemistry as the natural stone; simulants only look like it. Both are legal to sell when described as such.

Other lab-grown and simulants
Clasp & Lens describes materials from the public record and does not appraise, grade or test pieces; what a listing states is the supplier's statement. If a piece causes a rash, take it off; a reaction that spreads or blisters is a doctor's question, and sunglasses are no substitute for impact-rated eye protection where that is required.
