Eudialyte For Sale

Eudialyte is an uncommon ore of zirconium and the titular member of the cyclosilicate eudialyte group. Eudialyte is a minor gemstone, but rarely used because eudialyte often forms small, unstable crystals. Its name translates to “well decomposable” in Greek, which is an allusion to its solubility in acids. These crystals tend to form as glassy purple crystals that lean into the magenta portion of the spectrum. Their rarity and attractive coloring make them extremely collectable and valuable.

Eudialyte's exact chemical composition is hard to pin down because of its rarity and how closely related the group members are. This mineral is often collected in the rough and associated with aegirine and calcite crystals. This contrasting association makes polished specimens extremely visually appealing and highly sought after.

How Does Eudialyte Form?

This mineral predominantly forms in alkaline igneous rocks and areas with significant differentiation in magmatic intrusions near silica-rich environments. An excellent example of these locations are nepheline syenites, which are abundant along the Kola Peninsula in Russia. This variety in intrusions is perhaps the primary reason that the eudialyte group is so vast.

Where Is Eudialyte Found?

Eudialyte's rarity makes locality useful in its conclusive identification. Premier localities include Greenland, Mount Saint-Hilaire in Canada, the Kola Peninsula of Russia, and Brazil. Outside of these locations, a definitive identification of eudialyte is difficult to ascertain. Most of the highest quality eudialyte on the market is collected in Russia and is truly stunning to behold.

Common Associations

The Russian variety of this mineral is often found in association with aegirine and calcite. Other common associates are nepheline, microcline, sodalite, and magnetite. Of course eudialyte is often associated with other members of its group, such as oneillite, alluvaivite, and labyrinthite.
