C&S-Iolite-Genuine

At one end of the color spectrum lays fiery, brilliant red; at the other end is violet. The last color visible to the human eye, violet seems always on the verge of melting from sight. Few gems express the hue’s ethereal delicacy like Iolite. Its watery, purplish-blue can offer a tranquil escape or an uplifting experience, promising rejuvenation for its wearer. The stone must be very carefully cut, for Iolite is an extreme example of the color-shifting property called pleochroism. A cube of pure Iolite will appear violet blue from one side, clear from the other, and golden yellow from the top. This unique property helped guide the ancient Vikings on their legendary sea journeys: gazing through a thin disc of Iolite, they were able to tell by its shifting color the exact position of the sun. Iolite is a natural gem, meaning that its beauty is unaltered by human intervention with the exception of cutting. Found in India, Tanzania, Brazil, Sri Lanka, Madagascar and Namibia, Iolite is an affordable gem with great wearability. Its unique, misty color attracts shoppers of all ages, and it’s truly a color for all seasons.
