[Available 9/6 at 10 PM] Indian Iolite Sunstone 0.476ct Loose Gemstone
Iolite is known for its beautiful deep blue-violet color, reminiscent of a violet flower. It is a gemstone that exhibits "pleochroism," displaying different colors when viewed from different angles. This particular iolite features an optical effect known as aventurescence, which looks like glitter. It is commonly called "Iolite Sunstone" or "Aventurescent Iolite." Its sparkling blue-violet light is like stars shining in the night sky. Please enjoy this starry sky that you can hold in your hand. A penlight was used during photography.
This is an Indian Iolite Sunstone cut in a long hexagonal shape by the Sri Lankan gem cutter, Mr. Sanje.
