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.
Prasiolite, also known as vermarine or praziolite, is a transparent green quartz. Quite rare in nature, most prasiolites on the market are heat treated amethysts, which is why they are sometimes called "green amethysts". Not all heated amethysts result in green hued prasiolites, however. Only amethysts from a few select locations, including Montezuma, Brazil and Arizona, will produce prasiolites when heat treated. Naturally occurring prasiolite has been reported in Poland.
Prasiolite is considered by some to be a true collector’s gemstone due to its rarity. Relatively inexpensive, its popularity has grown in recent years with large, clean, color saturated stones as the most valuable and desirable. The color of prasiolite can vary from light yellow-green to deep green, and can look similar to peridot and tourmaline. Ranking 7.0 on the Mohs Hardness Scale, prasiolite is ideal for everyday wear. Clean the stone with warm soapy water and a soft brush while keeping it away from household chemicals. Prolonged exposure to extreme heat or sunlight may cause damage and discoloration. Store your jewelry in a fabric lined box and away from other items and gemstones to avoid scratching.
Derived from the Greek words, “prason” meaning leek, and “lithos” meaning stone, prasiolite was named for its vegetable colored stone appearance. Some believe prasiolite bridges the gap between physical and spiritual aspects of life and attracts prosperity by strengthening the mind and emotions. It is used by some as an aid for issues with the heart, digestion and even eating disorders.
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.
