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.

Useful conversions: 
1 dwt (pennyweight) = 1.555 grams
20 dwt (pennyweight) = 1 troy ounce = 31.1048 grams
14.583 troy ounce = 1 pound avoirdupois

In 1996, we experienced a fire and had to temporarily move our laboratory during reconstruction. In hopes of keeping things simple, we decided to only work with Maguire...because of the trust and relationship that was born, we now only use Maguire.
