This specimen is very intriguing for its chemistry (cesium rich), crystal habit, and luster. The luster is incredible, it is very flashy and was very difficult to photo. It is also complete all the way around - no contact points. It must have been a floater and as the Willard Roberts label states, it was found in a new pocket in 1949. It is not your typical Beryl crystal either as it is flat or tabular and has very complex faces.

Bikitaite is a very rare lithium tectosilicate and falls within the zeolite group. It is found in only three localities worldwide. This is the type locality, as the name would suggest. The specimen is practically all Bikitaite which shows many good platy, striated crystals to 1.5cm.
