NameMinesPropertiesPhenacite in Jewelry

Phenacite is is chiefly transparent, but seldom translucent or opaque gemstone, which is very similar to Beryl, however, due to its extreme rarity, the distinction between these gems has been discovered just in 1833. Phenacite is distinguished from Euclase and Beryl, thanks to its color, which is usually inferior with respect to Ecuclase, though the crystals that possessed a slight rose, brown, or wine-yellow inclining to red tint are occasionally met. And, nevertheless, Phenacite is unbelievably rare, as well as Euclase.


Phenacite Gemstone

The name of Phenacite (sometimes it is called Phenakite) is derived from Greek “phenax,” means a “deceiver.” Phenacite owes to its name, due to the fact that it has frequently mistakenly been taken for other gemstones, such as a Diamond, when it is transparent, for instance.


Phenacite is mined only in two locations in the world. Russian mines of Phenacite are located along the Tokovaya River, in the vicinity of Yekaterinburg in the Ural Mountains, where this gem occurs along with the Emeralds and Chrysoberyls, and in the Ilmensky Mountains, also so-called “Ural Switzerland,” thanks to their magnificence. The second known mines of Phenacite are located in the United States near Pikes Peak of mount Antero, Chaffee County, Colorado.

Some remarkable specimens sometimes meet on Bald Mountain, near North Chatham, New Hampshire. Some peculiar specimens of Phenacite were found in Brazil.

The specimens, obtained in Russia are larger than, those, obtained in the US and other locations. In the US, the crystals of Phenacite chiefly occur implanted on Quartz, Beryl and Feldspar.


The crystals of Phenacite possess splendid brilliancy, that could be described as “a borderline” between the Diamond and the Rock Crystal.

It can be distinguished from Quartz, due to its double-refraction and higher refractive index.

In regards to Phenacite’s shine and brilliance, it’s almost equal to the Diamond, however, is inferior to its other qualities.

Thus, the hardness of Phenacite is 7,5-8/10, according to the Mohs scale, that is much less in comparison to the Diamond, but it is superior to that of Quartz, this this is sufficient to compare Phenacite with semi-precious stones of the first grade.

Phenacite in Jewelry

Along with its “brother” Ecuclase, the Phenacite is seldom met in jewelry, however the jewelry made of it is distinguished by its exclusivity and rarity. Thus, the wearer of Phenacite can boast of the possessing of such rare gem.

Though, the specimens of Phenacite are chiefly spread among of many collectors, thus the Phenacite is principally a collectable gemstone, despite its semi-precious classification.
