Iolite stone

Iolite is a mineral gemstone that was discovered by French geologist Louis Cordier in 1813. It had been given different names before recognizing such as dichroite, water sapphire and known as the “Viking’s Compass,” which was one of the stones used by the Vikings for ocean navigation. It also seems to be two-colored stone which can appear to be different colors when viewed from different sides. In some directions, it may be sapphire blue while in another, it may be nearly colorless


lolite is found in many different locations around the world. Large amounts have been found in India, and good quantities have been recovered in Australia, the United States, Madagascar, Namibia, Tanzania, Burma, Brazil, and Sri Lanka

Color & clarity

The most common colors of iolite are blue-violet and a variety of blues that resemble blue sapphires. Faceted stones, calibrated cabochons, and beads of numerous styles, with a color palette of light blue, grayish blue, dark blue and blue-violet, can be found in a wide range of price points, making iolite an easy choice for many styles of jewelry

Cutting challenges

Because of the stone’s multicolored properties, iolite can appear to be three different colors when viewed from three different sides. Before it is cut, a rough piece of iolite can appear to be a sapphire-like blue from one side, colorless from another, and gray or yellow from another

This feature presents great challenge to the stone cutter as he must focus well in order to get the wanted color. Some iolite can have an “inky” dark color, and the gem cutter may cut the stone a little thinner to make the color appear lighter and more attractive. While this type of cutting improve the color, it diminishes the optical properties of the stone

At the end, iolite is a perfect choice for those who want natural, untreated gemstones for their jewelry. It is durable enough for all types of jewelry, including rings and bracelets
