Here at A Grain of Sand we just love the indigo violet hues of Iolite. These are 10mm Iolite rounds with that highly sought after matte finish. The shades of blue in these stones are absolutely mesmerizing. This beautiful stone is also known as "water sapphire". Iolite possesses an array of healing properties including; detoxification, assisting in the healing of nerves and eyes, and enhancing digestion. Very importantly, Iolite is said to shrink fatty deposits. Now, that's a fine quality for a stone to have.
