Silver (at least 92.5 percent pure silver) plated with gold. Where the plating has not fully bonded with the silver, the silver will tarnish underneath the plating, causing darkened areas to appear over time.
Gold-plating process developed in France in the mid-1700s. France banned production of vermeil early in the 19th century because the process involved the use of mercury. Present-day vermeil is produced by a safe electrolytic process.
A product that is made from a base of sterling silver that is coated or plated on its surfaces with gold of at least 10K and at least 2.5 microns thick (100/1,000,000 inch). The term vermeil cannot be used if the sterling is covered with a base metal before being coated with gold unless the presence of the base metal is disclosed.
(Vehr-MAY) A substantial amount of real gold which has been chemically bonded to sterling silver. The finish looks so much like solid gold that, except for the price, it is difficult to tell the difference.
