About

Jewelry Identifier

An AI-assisted jewelry identification tool, built by a small independent team for collectors, dealers, and curious owners. We help you understand what you have, what it might be worth, and how to care for it — while being honest about what AI can and can't do.

Our mission

Jewelry identification has historically required either years of training or an expensive trip to a gemologist. We think modern computer vision can make a first-pass identification accessible to anyone with a phone — not as a replacement for professional appraisal, but as a starting point that helps people make better decisions about pieces they already own.

Our content library exists to back up the app: when the tool identifies a stone or a metal, we want you to be able to read up on it and learn the underlying material so you can verify and form your own opinion.

How our content is researched and written

We're transparent about our process. Articles on this site are:

  • •Researched with AI assistance. We use large language models to synthesise reference material and structure articles. We disclose this rather than hide it.
  • •Cross-referenced against institutional sources. Standards, terminology, grading scales and historical claims are checked against the bodies listed below.
  • •Reviewed and edited before publication. A human reads every article and corrects errors, removes hallucinations, and adjusts tone before it goes live.
  • •Updated when we find mistakes. Found a factual error? Email us — we'll fix it and bump the article's dateModified so search engines re-crawl.

See our methodology page for a more detailed walkthrough.

What we are not

Honesty section — equally important as the mission. Jewelry Identifier is not:

  • ✗ A certified gemological laboratory
  • ✗ A substitute for a professional appraisal, especially for high-value pieces, insurance, or estate matters
  • ✗ A guarantee of authenticity — AI can be wrong, hallmarks can be faked, and photos miss things only physical inspection catches
  • ✗ A price oracle — value estimates are ballpark guidance from public market data, not appraisals

If a piece matters to you financially or sentimentally, take it to a certified appraiser. Our app is the starting point, not the final word.
