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.
Chrome diopside, also called Russian diopside, offers an intense forest green color. Because it is the most affordable gemstone with a pure, rich green color, many jewelry designers predict chrome diopside will be the world’s leading emerald substitute by the end of the decade. It is mostly available in smaller sizes, with the rare larger sizes becoming much more expensive and too dark. A 26.17ct oval cut chrome diopside may be the largest known example of the faceted stone, but there is also a 25.33ct stone that is brighter and more intense in color.
Chrome diopside is relatively soft, with a hardness of 5.5 on the Mohs Scale. Mostly mined in Yakutia and Siberia, the liberalization of the economy of the former Soviet Union has made chrome diopside more available, and more popular, than ever before.
Amber is fossilized resin from ancient plants, especially coniferous trees. Tens of millions of years ago, if the conditions were right, this sticky resin would become encased in earth and gradually become fossilized. Resin that has not completely fossilized is called copal.
Sometimes leaves, bits of wood, and even the whole bodies of insects would be trapped along with the resin. Pieces of amber with the intact remains of ancient insects or other small organisms are rare and highly valued. More than 1,000 extinct species have been identified in amber.
Jewelry and History
Amber is translucent and range in color from dark brown to a light lemon yellow. It is very soft, with a hardness of 2.5 on the Mohs Scale, and it can be scratched easily. Jewelry with amber cabochons should be worn with care to prevent damage to the stones.
Amber has been used as jewelry for thousands of years. Homer mentions amber jewelry—earrings and a necklace of amber beads—as a princely gift in The Odyssey. Amber can be burned, and this produces a strong aroma the ancient Germans used as incense; they called it bernstein, or "burn stone." Clear, colorless amber was considered the best material for rosary beads in the Middle Ages due to its smooth, silky feel.
Today, two main sources of amber are the Baltic Sea and the Dominican Republic. Amber from the Baltic states is older, but amber from the Dominican Republic is more likely to have insect inclusions.
A selection of our jewelry is made of sterling palladium alloy. Palladium is a member of the platinum group of precious metals. By replacing a portion of the copper content used in standard sterling silver with palladium, this proprietary formula renders a precious metal with superior performance attributes. Sterling palladium is five times more tarnish-resistant than standard sterling silver and has strength similar to that of 14K gold.
Palladium has been used as a precious metal in jewelry since 1939, originally as an alternative to platinum for making white gold. Its naturally white color requires no rhodium plating. Additionally, palladium is proportionally much lighter than platinum and is ideal for use in heavier gemstone jewelry. It is a more expensive alloy than nickel, but it seldom causes the allergic reactions that nickel alloy can.
