FAQs

Frequently Asked Questions: Colored Gemstones

Does natural mean untreated?

No. Natural origin and treatment are separate questions. Read the material designation and treatment wording individually.

Are all red gemstones ruby?

No. Several materials can appear red. Color alone does not establish a gemological identification.

Are all blue gemstones sapphire?

No. A blue appearance can occur in different materials. A precise identification is needed when the name matters.

Does every identification report include geographic origin?

No. Origin is a separate assessment, and availability or conclusiveness depends on the material and service.

Does a country-of-origin opinion prove the complete history of a stone?

No. Geographic origin and provenance describe different subjects. Ownership and supply-chain claims require their own records.

Does no indication of heating mean no treatment of any kind?

Do not broaden the wording that way. Retain the report's exact scope and ask for clarification if necessary.

Are AAA and similar labels universal gemstone grades?

Do not assume they are. Ask who defined the label and which criteria it represents, then compare it with the laboratory information.

Does a result for one bead apply to an entire strand?

Only rely on the scope explicitly stated. Ask whether the examination covers all components or selected items.

How should I clean a gemstone with an unknown history?

Seek advice appropriate to its identity, treatment, condition, and setting before choosing a method. Avoid assuming all jewelry can be cleaned alike.

Can an educational article identify my own stone?

An article explains concepts. An item-specific conclusion requires the appropriate examination and report.
