PHTHALO NO. 1
I don’t always love blue, but when I do. it’s because it has something special. This is kyanite. A complex and beautiful stone. Kyanite is anisotropic which means it has a dual hardness on the Mohs scale, depending on which axis is being measured. Much like us.
Kyanite is usually found in long bladed crystals and when cut can have inclusions of different crystal habits. These help make the character of these stones more unique.
