Synthetic gem products
Manufactured products having essentially the same chemical, physical and structural properties as their natural counterpart; qualifiers such as synthetic or laboratory-created are required.
What this family is
Membership turns on one test: does the manufactured material match its natural counterpart in composition, physical behaviour and crystal structure? The qualifier — synthetic, or laboratory-created — must sit immediately adjacent to the name; a manufacturer's name is no substitute for that disclosure.
Products with no ordinary natural counterpart, cubic zirconia among them, are classified as artificial instead.
Scope of this family
Manufactured products having essentially the same chemical, physical and structural properties as their natural counterpart; qualifiers such as synthetic or laboratory-created are required.
CIBJO definitions
- Synthetic stones
artificial products having essentially the same chemical composition, physical properties and structure as that of their naturally occurring counterparts. NOTE – The term “synthetic”, “laboratory-created” and “laboratory-grown” are synonymous. See clause 4.3.3.2. However in the event the national jewellery association, which is a member of CIBJO, deems that there is no acceptable local direct translation of the English terms “laboratory-created” or “laboratory-grown” then only the translation of the term “synthetic” should be used.
