Iolite or cordielite is a widespread mineral discovered and named after a French geologist P. Louise Cordiere in 1813. It belongs to the cyclosilicate group rich in aluminium. This piece is from India.

Iolite uniqueness: Iolite is noted for its blue, to blue-green shade. The high-quality pieces from India are suitable for further processing.

Special conditions/ treatment: Iolite is stable against most acids.

Use: Our rough stones are a beautiful interior adornment – filling up a vase, fountain or a lamp with them creates an original design. In the exterior, they may be a perfect decoration of gardens. They are also suitable for mineralogist collections and exhibitions. Rough minerals may also be further processed, e.g. small crystals are ideal material for pendants.
