How We Test Gold
A transparent look at the testing process behind every gold offer we make.
Understanding Karat Markings
Gold purity is measured in karats, out of a possible 24: 24k is 99.9% pure gold, 18k is 75% gold, 14k is about 58.3%, and 10k is about 41.7%, the minimum legally sold as “gold” in the U.S.
How We Test Your Gold
Visual inspection starts with any karat stamps or hallmarks, which we then verify with testing. Acid testing uses solutions calibrated to specific karat levels on a small, unnoticeable area. Electronic and XRF testing measures metal composition without damaging the item at all for higher-value pieces. Once purity is confirmed, we weigh your item precisely and calculate your offer from the actual pure gold content at the current market price.
What About Gold-Plated or Gold-Filled Items?
These items contain only a thin layer of gold over a base metal and generally have minimal scrap value compared to solid gold. We’re happy to evaluate them, but expect a much lower offer than for solid gold pieces of similar size.

Frequently Asked Questions
Does gold testing damage my item?
Acid testing is done on a small, unnoticeable area, and modern electronic or XRF testing doesn’t damage the item at all.
What if my gold isn't stamped with a karat marking?
We can still test and determine the purity directly, a karat stamp isn’t required for us to evaluate your item.
Is gold-plated jewelry worth anything?
Gold-plated and gold-filled items have much less scrap value than solid gold since they contain only a thin gold layer, but we’re happy to evaluate them.
How is my final offer calculated?
We multiply the item’s weight by its confirmed purity percentage to determine pure gold content, then price that against the current market rate for gold.
Can I watch the testing process?
Yes, evaluations happen in front of you during your appointment.
Do prices change based on the day I sell?
Yes, gold is priced on a global commodity market that moves throughout each trading day, so your offer reflects current market pricing.
