The "vermeil" technique of plating sterling silver with gold originated in France in the 1750s. It differs from "gold filled" or "gold plated" in terms of the thickness or thinness of the microns over sterling silver. "Gold filled" pieces have a much thicker layer, between 15 and 45 microns, which is mechanically bonded to the base metal with heat and pressure. Vermeil is a more expensive version of "gold plated". It does not wear off as quickly as gold plating does. However, over time, vermeil wears off and therefore will require re-plating.
Over time your plated items will need to be re-plated. Contact your local jeweler for information on plating services.
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.
Morganite is the soft pink, sometimes peach or lavender colored, variety of beryl. Often referred to as “pink beryl,” morganite has been called "pink emerald" and "pink aquamarine" to emphasize the kinship to its popular cousins. The pastel gem is colored by trace amounts of manganese in the crystal structure. It has excellent fire and is dichroic, meaning it shows pink hues when viewed from one angle and near colorless properties from another. Almost all morganite is heat-treated to produce or enhance the pink color. Lower quality morganite occurs in colors ranging from a peach-orange to a pinkish-yellow, but once it’s heat-treated, the color changes to a beautiful soft pink.
First discovered in Madagascar in 1911, morganite was named after the American banker and gem enthusiast, John Pierpont Morgan. Legend says that he went down with the Titanic, but Morgan actually missed the doomed maiden voyage and died the following year in Rome, just shy of his 76th birthday. While morganite can be found in Mozambique, Namibia, Afghanistan, Russia and the United States, the finest morganites come from Madagascar and Brazil. In fact, the largest faceted morganite came from Madagascar. It is a 598.70ct cushion-shaped stone residing in the British Museum.
Morganite’s hardness ranks 7.5-8.0 on the Mohs Scale . With its dazzling luster, exquisite color and sufficient hardness, the stone is especially suitable for jewelry. Unfortunately, morganite is relatively rare. This fact alone prevents it from achieving greater popularity as a jewelry gem.
