Gemmology and industry updates

Research changes how gemmologists investigate materials and communicate their findings. Start here for reliable reading and the questions behind the headlines.

Laboratory-grown materials

Growth methods and identification techniques continue to develop. Ask what a report establishes about a stone’s identity and which questions require further testing.

Treatments and disclosure

Treatments can affect appearance and care. Read the comments on a report and ask for clarification when a description or trade term is unfamiliar.

Read the original research

For an industry headline, look for its original laboratory publication, publication date and the materials actually examined. Findings for one sample do not automatically apply to every gemstone.
