Very clean Cordierite cabochon - gem quality (or also after the old Iolith). It has a mystical gray-blue-purple special color similar to frosting on blueberries. The color changes with the angle of view. Price per set.
The color matches beautifully with the sun stone! Great and very original duo. (Day and night)
Cordierite is one of the gems and in addition has a beautiful hardness - 7-7.5 (same hardness as tourmaline)
Like all purple stones, they belong to the realms of intuition, will, and crown chakras. It's a very mysterious, night stone. It will be great for interesting dreams and meditations.
