Estimated delivery between 26 November and 01 December.
We have for you a large Duckbill style gypsum var Selenite from world famous Red River Floodway in Winnipeg, Manitoba Canada. This is a large floater gypsum crystal cluster that occurred in the Pleistocene Age in Lake Agassiz clay. The distribution of the gypsum covers a 20 kilometer wide area, but the Floodway is one of the few excavations in the very flat terrain deep enough to intersect the gypsum layer.
The Red River Floodway has become famous, not only for its engineering marvel but also for the extremely unusual selenite specimens that were discovered during excavations. The formation is due to two generations of growth with the first growth forming near-spherical rosettes of stout intergrown crystals and the second growth, that made them famous, grew large golden crystals with a unique twinning shape that resembled a duck’s bill. These “duckbill” selenites are famous the world over and have found nowhere else in the world to date and collecting is now carefully controlled. Specimens range from having a single crystal, to having many radiating from the rosette. Some rare examples have two rosettes conjoined in striking formations. This specimen is in excellent condition.
