The field guide behind MarkSnap

About MarkSnap

MarkSnap is built for the moment when a promising piece is in your hand, the price tag is staring back, and there is no reliable signal in sight.

Our Mission

We turn dense vintage jewelry identification knowledge into fast, visual field references for estate sale pickers, thrift flippers, resellers, and collectors. Our pocket deck helps you recognize useful clues—from sterling marks and plating terms to stone indicators and maker hallmarks—before you decide whether to buy.

Designed for the Hunt

The physical deck uses water-resistant, credit-card-sized references held on a brass ring. A bundled offline mobile PDF and printable edition keep the same checks close wherever you source.

A Better First Pass

MarkSnap is an educational screening tool, not a formal appraisal or guarantee of authenticity. It is designed to help you ask better questions, avoid obvious misses, and know when a find deserves expert attention.
