Optional details you know first-hand

Tell us what you measured yourself, what someone told you, and what a report says — we keep these separate.

Privacy: photos are used only for your scan, location data is removed before upload, and nothing is used for training unless you opt in. Guest scans are deleted after 24 hours.

What you get

Evidence, not a verdict.

Explore likely matches

Compare candidate identities and the observations that support or weaken each one.

Inspect visible condition

Record chips, surface wear, apparent colour and features visible in your photographs.

Understand verification

See which questions need measurements, microscopy or a laboratory report.

Build your collection

Keep photographs, notes and supporting documents together as you learn more.

Three different questions

Identity, origin and treatment are separate. A photo can help with the first; the others usually need testing.

Natural

Formed by nature. May still be treated.

Laboratory-grown

Same material, grown by people. A lab-grown diamond is diamond.

Imitation

A different material made to look like something else, such as glass sold as ruby.
