Stone & jewelry observation sheet

1. Record the object

Date: ____________________   Object / specimen number: ____________________

Found, inherited or purchased? Where? _______________________________________

Dimensions: ____________________   Loose or mounted? ____________________

2. Take useful photographs

• Whole object on a plain background.
• Another angle, including the reverse if accessible.
• Close-up of visible natural surfaces, patterns or marks.
• A separate view with a ruler for scale.

3. Write only what you can observe

Color in daylight: __________________________________________________________

Shape / visible grains / bands: ______________________________________________

Natural, worn or polished surfaces: __________________________________________

Jewelry marks, exactly as visible: ____________________________________________

4. Keep candidates provisional

Possible identity: ____________________ Suggested by: ________________________

Observations supporting it: __________________________________________________

Alternative to compare: ______________________________________________________

Unanswered question: ________________________________________________________

5. Choose a next step

Use the mineral guides, stone comparisons to narrow your question. An app suggestion is a candidate, not an independent confirmation. Ask a qualified examiner when identity, treatment, authenticity or value matters.

Do not scratch, acid-test, heat or break jewelry or a valued specimen to fill in this sheet. Record an unknown property as unknown.
