Weloganite on Calcite (Schlichter Coll.)

Item Description

Weloganite is an ultra rare, strontium, sodium, zirconium carbonate and this showy and excellent specimen is from the famous Type Locality - the now-closed Francon Quarry in Montreal, Quebec. An 8 mm, doubly terminated, tapered and layered, off-white crystal is aesthetically set on the calcite crystal covered sculptural limestone matrix. A fine and showy example, this extremely rare species is known at its best from a very few pockets at this cement quarry, which has incredibly strange chemistry and has produced a number of such rarities IN THE PAST. Not available now, except from advanced recycled collections. Ex Ernie and Vera Schlichter Collection. Note that the crystal is yellow inside but is covered by a microthin layer of other rare species.
