Pronounced “vermay,” vermeil gold is the way heavy 14K or higher gold that is electroplated over sterling silver is officially designated by the industry. Items may only be marked or sold as vermeil if they have a minimum thickness of 100 millionths of an inch of gold or 2.5 microns of gold.

Gold plating is an electrolytic process in which a gold coating of at least 10K gold with a minimum thickness is affixed to all surfaces.

Gold-filled jewelry consists of a layer of 10K gold or better mechanically bonded to the surfaces of a base (non-precious) metal. This layer of 10K gold must be a minimum of 1/20th of the total metal weight to be called gold filled.

Over time, gold plating and vermeil will wear off, requiring re-plating.

Onyx:

Onyx is a variety of chalcedony quartz that features a fine texture with a smooth black color. Some onyx can display white bands or ribbons against black or brown backgrounds. Mined in Brazil, India, California and Uruguay, most onyx today is color-enhanced to increase its depth of color. It ranks a 6.5 on the Mohs Scale and is an ideal stone for carving. In fact, it is a favorite material of lapidary artists.

Onyx was very popular with the ancient Greeks and Romans. The name comes from the Greek word “onux,” which means fingernail. Legend says that one day frisky Cupid cut the divine fingernails of Venus with an arrowhead while she was sleeping. He left the clippings scattered on the sand and the fates turned them into stone so that no part of her heavenly body would ever perish. In Greek times, almost all colors of chalcedony were called onyx. Later, the Romans narrowed the term to refer to only the black and dark brown colors, while the reddish brown and white onyx became known as sardonyx. Highly valued in Rome, sardonyx was especially used for seals because it was said to never stick to the wax. Roman General Publius Cornelius Scipio was famous for wearing sardonyx.

Worn during mourning in the Victorian age, onyx is now traditionally given as a 7th wedding anniversary gift. It is thought to increase happiness, intuition and instincts. The stone is also believed to cool the yearnings of love and decrease sexual desire.
