Picture What's Foil Backed gemstones? Foil backing (or foiling) is a gemstone surface enhancement technique where a thin sheet of metal or other material (sometimes colored) is placed behind the gemstone in order to reflect more light, and/or color, back into the stone and then towards the viewer. Therefore, the foil acts both as a reflector and a coloring agent. Most foiled gemstones are set in closed backs to shield protect the foil from deterioration (and detection?). A thin metal foil placed behind a gemstone within a closed-back setting to improve its optical performance. Metallic foil improves the reflectivity of certain gemstones, whilst coloured foils act as colouring agents when placed behind colourless materials, such as paste and rock crystal. These stones were typically set in silver closed backs to shield the foil from deteriorating. The practice of foil-backing gemstones can be traced back to Minoan times (circa 2000 BC), however it is most closely associated with the Georgian and early Victorian periods. What kinds of gemstones can be foiled back? There're many kinds of gemstones can be foiled back. The cheapest ones are rhinestone and then Glass gemstones, crystal stones. And also Cubic Zirconia gemstones which is sparkling & brilliant. and Corundum gemstones, Spinel, Nano Crystal and many kinds of synthetic and natural gemstones can be folied /coated back.
