Precious Metal Calculator
Helping you estimate the value of your gold and precious metal scrap
Our precious metal calculator is intended for use by our in-the-trade jeweler customers that have storefronts and state and federal ID numbers. If you are a member of the general public and would like to inquire about our services, please call us at 800.486.2858 or contact us.
Please note that the US Hallmark Act of 1981 requires manufacturers to fully karat gold solids; prior to 1981, manufacturers could by law be 0.5 karat light. Therefore, jewelry manufactured prior to 1981 may have been legitimately under-karated, slightly lowering the expected gold return of a settlement.
We are unable to estimate the value of dental solids made from precious metal alloys, since there is no standard gold percentage for dental solids.
