We fixed a few bugs and made Gemmo more reliable.

New: Offer check. Selling a piece? Type in what a buyer offered and Gemmo shows how it compares with the piece's melt value — and the least you should ask for — before you say yes. Part of Gemmo Premium. Also in this update: • A cancel button while a scan is running. • "Scan another" now respects your free scans, and restoring purchases tells you what it found. • Clearer text and controls in light mode, and the purity scale no longer clips at 24K. • If a PDF export ever fails, Gemmo now tells you instead of doing nothing.

A few more improvements to Gemmo, and a scanner that reads your jewelry more accurately. Gemmo now recognizes plating marks. A stamp like GP, GF or HGE means the gold is only a surface layer, and Gemmo says so instead of pricing the piece as solid. Pieces with no hallmark at all now get a value too — antique bands, inherited chains, anything whose stamp hides inside a clasp. Gemmo shows what grade it assumed, and you can set the right one in a tap. Every figure now tells you where it came from: read from a hallmark, set by you, or assumed. Only what Gemmo could genuinely read off a stamp goes into your insurance PDF and your collection total. Scans are faster, too.
