Blue Dumortierite Slab

Dumortierite can sometimes be mistaken for sodalite and lapis lazuli; however, it's harder than both of those materials and therefore more durable for jewelry; it's also likely to take a higher polish. It displays a fantastically rich, denim-blue color - a great way to get such a vibrant color in a relatively hard material (MOHS 7-8).

This is a rough, unpolished slab. Please observe images closely for flaws, as some degree of that is normal. Pictured wet and dry.
