Dumortierite Stone Glossary

Dumortierite is a durable aluminum borosilicate mineral valued for its deep blue to violet hues, often featuring subtle mottling or streaks. Dakota Stones offers dumortierite beads that are well-suited for jewelry designs requiring both visual interest and structural integrity. Its relatively high hardness and resistance to wear make it a practical choice for bracelets, necklaces, and earrings. Dumortierite's natural color and texture provide a sophisticated alternative to more common blue gemstones, and its availability in various shapes and sizes supports versatile design applications.
