About

Jewelry Identifier

An AI-assisted jewelry identification tool from Ideas All Day Ltd. for collectors, resellers, and curious owners. It helps organize visible clues and possible next steps while staying explicit about what a photograph and an AI model cannot prove.

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

The library uses a source-first publishing standard with article-specific citations and explicit provenance. We do not treat an AI draft as evidence, and we do not imply professional review when none occurred.

• •AI use is disclosed. Models may help structure a draft, but they are not cited as factual sources.
• •Sources must match the claim. New technical guides link the exact primary or standards-setting pages used. A general institution list is not presented as article-specific proof.
• •Review status stays explicit. We list a reviewer or fact-check state only when that work is recorded. Every indexed educational article currently carries article-specific sources, provenance, and explicit index approval.
• •Corrections are welcome. Found a factual error? Email the page URL and supporting source. We will correct it and update the page date when the underlying content changes.

See our methodology page for a more detailed walkthrough.

What we are not

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, use a qualified independent appraiser or appropriate laboratory. The app is a starting point, not the final word.

Primary and standards-setting references

We consult these sources when their scope matches a claim. Listing them does not imply endorsement, partnership, or that they reviewed Jewelry Identifier.
