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.

Coral:

Most people think the coral used in jewelry comes from South Pacific coral reefs such as the Great Barrier Reef off Australia. However, these coral reefs are formed by a different species than the coral that is traditionally used in jewelry. Most jewelry coral is found in the Mediterranean Sea or in the Pacific near Japan and Taiwan. It grows in ocean colonies of branches that look like underwater trees, and is found in a range of colors, including pale pink (called angelskin coral), orange, red (called noble coral), white and black. The most valued colors are deep red, black and pink. It is much softer than other gems, with a hardness of only 3.5 on the Mohs Scale. In jewelry-making, coral is often carved into beads or cameos, or can be left and polished in its natural branch-like form.

Among the most ancient of gem materials, coral has been used for adornment since prehistoric times. While coral inlays and ornaments have been found in Celtic tombs from the Iron Age, the gem also has a history of religious significance. It is one of the seven treasures in Buddhist scriptures, and coral rosaries are used by Tibetan Lamas.

Coral was long thought to be a powerful talisman that could stop bleeding, protect from evil spirits, and ward off hurricanes. Because it was believed that coral protected the wearer, it was a traditional gift to children. Coral was also believed to lose its powers once broken. Today, coral is the traditional 35th anniversary gift for married couples.
