Natural Iolite Ring

Natural Deep Blue/Purple Iolite No treatment, mined in Madagascar 0.48ct Marquise Cut 8mm L x 4 mm W Rhodium over 925 Sterling Silver Size 5 New in Box Iolite is the gem-quality blue or blue-violet variety of cordierite. While iolite enjoyed popularity in jewelry in 18th-century Europe, this naturally beautiful gemstone is relatively new to today's jewelry market, and is regaining popularity with the public. Because of its varying levels of hardness and strong pleochroism, iolite is one of the most difficult stones for lapidaries to fashion. It must be cut in certain directions to take advantage of the best color, which can be tough when the shape of the rough doesn't lend itself to cutting in that same direction.
