• IOLITE

  Iolite is usually a purplish blue when cut properly, with a softness to the color that can be quite attractive. It is more common to find iolite with beautiful blue in small sizes: larger sizes are often too dark, almost black. Iolite is readily available and surprisingly affordable in sizes up to 4 or 5 carats. The better and richer the blue, the higher the price. Colors that are gray, purple, or less saturated blue are less.

  Iolite is mined in India, Sri Lanka, Mozambique, Zimbabwe, and Brazil. The Vikings probably mined iolite from deposits in Norway and Greenland. The most common shape is oval.

  Iolite is relatively hard, with a Mohs Hardness of 7 to 7.5, but should be protected from blows. Clean with mild dish soap: use a toothbrush to scrub behind the stone where dust can collect.
