Phenakite

Uncommon mineral, beryllium silicate, Be2SiO4, used as a gemstone. Phenakite has lengthy been recognized from the emerald and chrysoberyl mine on the Takovaya River, near Yekaterinburg (previously Sverdlovsk), within the Urals area of Russia, the place giant crystals occur in mica schist. It also occurs within the granite of the Ilmen Mountains within the Urals and of the Pikes Peak area in Colorado. Other notable localities include Kragerø, Norway, and San Miguel de Piricicaba, Brazil.

For gem purposes the stone is brilliant cut-i.e., with quite a few facets. It is often colourless and glassy but may be wine yellow, pale rose, or brown. Its indices of refraction are higher than these of quartz, beryl, or topaz; it's consequently moderately sensible and should generally be mistaken for diamond. Nonetheless, it's not basically use, and tremendous examples are seldom seen outdoors personal or museum collections.
