Physical properties

Hardness: 5-5.5; Color: Pink, red, or magenta crystals in black/grey matrix; Luster: Vitreous; Crystal system: Trigonal; Specific gravity: 2.7–3.0.

Formation & geological history

Formed in alkaline igneous rocks like nepheline syenites and pegmatites. It is an end-stage crystallization mineral often found in late-stage magmatic fluids.

Uses & applications

Primarily used as a minor ore of zirconium. It is highly valued as a collector's mineral and occasionally used in jewelry as cabochons or decorative carvings.

Geological facts

Eudialyte is often called 'Dragon's Blood' in certain spiritual circles. It is unique because it can contain high concentrations of rare earth elements and is often mildly radioactive due to trace amounts of uranium or thorium.

Field identification & locations

Identify by its distinctive magenta or crimson spots within a dark matrix (often containing aegirine or feldspar). It is commonly found in the Kola Peninsula (Russia), Greenland, Canada, and Arkansas (USA).
