Dumortierite Crystals Grade A

Dumortierite is a natural mineral that occurs in metamorphic rocks rich in aluminium.  The finest material often features a mass of long slender crystals embedded within the mineral quartz.

Commercial grade dumortierite is quartz heavily included with dumortierite.

These grade A dumortierite tumbled stones have a relatively even distribution of colour.  We also have grade C dumortierite in our collection.  They're a lower grade because impurites cause additional colour and markings. 

Dumortierite was first identified as a mineral in 1881.  It was subsequently named after French palaeontologist Eugène Dumortier [1803-1873].  When newly discovered minerals are named after a person or a place it's quite common for the suffix 'ite' to be used.

Examples include charoite, labradorite, morganite and englishite to name just a few.  

These dumortierite crystals are size medium.  Size can vary from piece to piece.
