A single gem transparent crystal from the old 1970s finds at Djemaa, not to be confused with other finds on the Jos region of Nigeria. This crystal masses about 3.5 grams and displays as a full size thumbnail. Note the distinctive sharp and prismatic termination with a flat pinacoid atop. This is a stunning gem crystal from a highly unusual old locale, from the diverse beryl collection of Bill Larson (building since the late 1970s).
