3) Term “gold” can only be used if gold content is 10 K or better.

4) Term “gold filled” applies only to items composed of a layer of gold pressed (not alloyed) onto a base metal where the weight of the gold comprises at least 1/20th of the total weight of the item.

5) Term “rolled gold plate” is the same, but gold comprises less than 1/20 of total weight; e.g. stamped “1/30 12 k G.P.” means 1/30 of the metal weight is from 12 karat gold plate.
