Elpidite - Na₂ZrSi₆O₁₅·3H₂O, Leifite - Na₇Be₂(Si₁₅Al₃)O₃₉(F,OH)₂

This specimen is composed of a large cluster of gray colored Elpidite crystals covered with small Rhodochrosite crystals. The Elpidite crystals have an elongated, needle like habit with a slight, silky luster. The Rhodochrosite is a dark, red/brown color and has a high glossy luster and a platy habit. There are also two Leifite crystals present, which look similar to the Elpidite, but are white in color and have more luster (see the third from last photo).

Condition: Good

Flaws: Some of the Rhodochrosite and Elpidite crystals are incomplete which is not readily noticable.
