Recycled gold fell 6% in the second quarter of 2026, even though prices were far above last year. What that says about selling old gold, and how melt value is worked out.
Four coached photos, an optional size reference and weight, values based on the live spot price, and a confidence figure that explains itself.
Where to find the marks on a piece of jewellery, how to photograph them for a scan, and why even a convincing stamp cannot tell you what it is worth.
A new look in light and dark, the free Value Checker, and purchases, plans and exports that work the way they should.
The guided scan takes several photos of one object. How to choose which views to add.
Guided scans, Ask karat, the free Value Checker and five free scans for every new account.
One object per scan, several photos of that object, and why mixing items goes wrong.
Weight, provenance and what you already know: the details a photo cannot carry.
How close to get, how much to crop, and the mistakes that cost you a usable result.
A coin, a scale and a ruler will do more for your results than any camera upgrade.
