What we buy

Platinum.

Mounts, findings, bench scrap and lab material, in .999, .950 and .900.

Platinum is the grade most often guessed at, because white gold and palladium alloy look like it under a loupe and a stamp is only as good as whoever struck it.

How it is assayed.

The lot is weighed in front of you, then read on XRF. The XRF reading is what separates platinum from white gold and from palladium alloy, and you watch it taken.

Plated and gold-filled material is not bought at all. It is refused. It is separated out at the counter while you watch it come out, and it goes back across the counter with you.

White metal goes in and XRF separates it into platinum, white gold and palladium alloy, each settled on its own terms. White metal in XRF Platinum settled as platinum White gold settled as gold Palladium alloy settled separately A stamp is only as good as whoever struck it. The reading governs, not the mark.

White metal goes in and XRF separates it into platinum, white gold and palladium alloy, each settled on its own terms.

What XRF separates
