Mostly gem, this specimen measures in at 1.7 x 1.6 x 1.4 cm. Basically impossible to find this material any longer and it was rare in the first place. This is a very rare double terminated crystal. Collected by museum staff in 1982. Zero damage. This is a doubly-terminated crystal.  Outstanding luster, transparency, and overall, a fine example when compared to similar material from the find and other world-wide localities.
