Describe what you know.

You can start with “a ring with a green stone.” Color alone does not identify a gemstone. Share any existing laboratory report, receipt or appraisal, plus known repairs or damage.

Look at stone and setting together.

Identity, size, condition and treatment information can matter for a colored stone. The metal, maker and construction also affect the complete jewel. Keep stones in their settings until a specialist has examined them.

Useful photos and documents.

  • The complete piece in ordinary light.
  • Readable marks inside a ring or near a clasp.
  • Existing reports, including their identifying numbers.
  • Visible chips, wear or past repairs you already know about.

Photos help start the conversation; the in-person examination answers questions they cannot.

A loose stone or an unfamiliar material?

Ask the SDJB team about it before making a special trip. They can explain what information would help and whether independent laboratory work is useful. You do not need to buy a new report just to start an inquiry.
