So i have been playing around with density tests on some past finds. Basically, you find the mass and then find the volume and divide the mass/volume to get the density. Then look the density up on a chart based on the alloy that the ring is and it should match up to determine the metal type used. So 2 rings that I found last year that were originally thought to be silver ended up being white gold. One was marked 825 with no other marking weighing 3.73 grams. I thought it was 925 but after doing the density test, it had a heavier density which matched up on white gold. I looked closer at the stamp and it was actually 825. Woohoo. So i decided to check another ring that i was unsure of which was stamped 925 with a circle K (usually meaning gold) and turned out to be white gold as well. Pleasantly surprised. Waiting for my chem tests to be delivered in the mail and will verify.
