Eudialyte is a rare and complex silicate mineral that forms in granular pattern. It was first discovered in 1819 in Greenland and named after the Greek words “eu” meaning “well” and “dialytos” meaning “dialytic” because of its ready solubility in acids.
Eudialyte has also been found in other locations worldwide such as Russia, Canada, Norway, Madagascar, and the United States.
Eudialyte is primarily found in alkaline igneous rocks including syenite and nepheline syenite.

Eudialyte is a complex silicate mineral that typically has a granular or massive crystalline structure. It possesses a hardness of around 5 to 6 on the Mohs scale and has a specific gravity ranging from 2.8 to 3.1.
The stone displays a range of colors, including shades of pink, red, brown, yellow, and sometimes black. Eudialyte is known for its vibrant and distinctive patterns, often characterized by zoned or mottled arrangements of colors.
