Methodology

How our guides are researched

Published by The Apptor, written and edited by The GemPeek Editorial Team.

Where our information comes from

Our jewelry identification, gemstone identification, jewelry appraisal guides are built from documented references: published catalogs, recognised reference works, and reputable sale records. Where where available, from GemPeek's own aggregated, de-identified identification data. Every specific claim is grounded in a real source; we cite it on the page rather than asking you to take our word for it.

How we use AI

We use AI to help draft and organise content, but it never originates facts. Figures, dates, makers, and identifying details come from the sources above. AI only helps summarise and explain them, and a person checks the result before it is published.

About value estimates

Any value we show is an estimated range with its source and date, not a guarantee or a professional appraisal. Condition, rarity, and the market move prices, so treat estimates as a starting point and seek a qualified appraiser before buying or selling anything significant.

Corrections

We want to get this right. If you spot an error, tell us and we'll review it against the sources and update the guide.
