14K Rose Gold Victorian Blue Banded Agate Ring
Located in Venice, CA
This is an elegant Victorian era ring, featuring the popular Scottish stone of banded agate. The banded agate is smooth and could be engrave with a personal sign or emblem, potentially making it a signet ring. The oval and smooth banded agate gemstone measures 3/8 by 5/8 of an inch. It is a very dark blue color, and the sides, where one can see the rings of the agate, is a darker black color. The band on the ring is banded also, with a nice texture that enhances the qualities of the stone. The rose gold color is a nice choice to set off the darker and moody gemstone. The ring is a size 4.5 but could be easily resized. Feels great to the touch making this a great everyday ring. The ring remains unmarked but has been acid tested to 14K gold. Weighs 3.65 grams.

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...
