The 3 qualities of gold plated jewelry ie Millefiori

Micron gold plating is the same technique used to form gold vermeil; in vermeil a layer of at least 2.5 microns of gold (also referred to as heavy gold plating) is deposited onto silver but the term micron gold plating in general refers to the depositing at least 1 micron of gold onto a base metal like brass.
