Vernis Ember Flame Feldspar(Tm) Average 3.50ct 10x10mm Square Cushion, Quantum Cut(R) Kadenze Collection(Tm) .<br/><br/>Jewelry Television's goal has always been, and continues to be, to open the world of fine jewelry and gemstones to you, our valued customer. As we strive to bring you the most innovative gemstone products available, we are pleased to bring you natural gemstones that have been enhanced via a 21st century process. This process is known as Vernis, meaning "icing" or "glaze" in the French language. Much like the baker knows his decorator cake isn't complete without the frosting, the Vernis process deposits a surface coating of vivacious, durable color on natural gemstones, often giving them brilliant colors they aren't typically known for. Under normal wear conditions, avoiding heat and harsh chemicals, polishing or recutting, your Vernis gemstone will delight you for years. We invite you to add these confectionary gem delights to your collection today. Available in loose gems as well as expertly crafted fine jewelry, our Vernis collection is sure to excite even the most ardent of collectors! Treat yourself today to Vernis, available exclusively at Jewelry Television and jtv.com. As a late evening fire once ablaze with brilliant colors begins to smolder, what remains are burning embers glowing radiant shades of orange against the twilight backdrop. Today, Jewelry Television introduces Vernis Ember Flame Feldspar, our embodiment of those brilliantly colored embers in a beautiful gemstone. Yet, you don't have to wait until the evening hours to enjoy it; this gem's vibrant color dazzles 24 hours a day! We have taken the inherent beauty of crystalline labradorite feldspar and deposited a coating of vivacious, durable color on the gem's surface. The result is a beautiful gemstone that will give you many years of enjoyment. If you choose to set your gem into jewelry, please remember to let your jeweler know to refrain from heating it with his torch, cleaning with harsh chemicals, repolishing or recutting it. For those who love transparent, brilliant gems in a color Feldspar isn't normally seen in, look no further than Vernis Ember Flame Feldspar! And you'll find it only at Jewelry Television and jtv.com. The name Kadenze(TM), inspired by the French word 'cadence', refers to rhythmic balance and measure. Exclusive to Jewelry Television(TM), the Kadenze(TM) collection features specialty cut gemstones fashioned with the perfect balance of art and science. Only the very finest natural gemstones have been selected to be fashioned into cuts rarely, if ever, seen in the market. Expertly calibrated, each Kadenze(TM) gem is a testament to the fine art of faceting and its amazing results.
