Please avoid identifying a stone with certainty from appearance alone. Some materials require professional gemological testing, and laboratory-grown stones can share many properties with their natural counterparts.

For sellers: Be precise about the material, treatments and any claims you can substantiate. For buyers: ask questions before committing to a purchase.
