Antique Georgian Garnet 14K Yellow Gold Signet Ring, 19th Century
Located in New York, NY
An ancient gemstone, garnet has been revered by the Egyptians, Greeks, Romans, Anglo-Saxons, Medieval Crusaders, Hunza warriors, Kings and Queens. It has historically been associated with the heart, inner fire, love, friendship and vitality. Amulets using the stone have been discovered in Egyptian tombs, were used by the Romans to seal important documents and worn into battle by both Christian and Muslim warriors to protect against injury. King Solomon is said to have worn garnets into battle and Queen Victoria and Mary Queen of Scotts wore garnet jewelry, purportedly for protection. Carl Faberge designed jewels incorporating garnets for the Russian court, including the striking demantoid, almandine and carbuncle varieties. Prior to the nineteenth century, blood-red cabochon cut gemstones such as rubies, spinels and garnets were considered to be the same type of stone and were refered to as Carbuncles. A fascinating history, beautiful color and rich symbolism make this gemstone an excellent choice. Garnet signet rings are quite rare due to the desirability of this beautiful gemstone. This ring features a deep, rich ruby red octagonal garnet...
