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.

We have for you a small floater crystal of gypsum var Selenite in a perky box found 1962 in Ellsworth Mahoning County, Ohio U.S.A.. 

Gypsum is one of the more common minerals in sedimentary environments. It is a major rock forming mineral that produces massive beds, usually from precipitation out of highly saline waters. Since it forms easily from saline water, gypsum can have many inclusions of other minerals and even trapped bubbles of air and water.

This specimen has no damage and will ship in its protective display box.

Gyrolite often forms nodular aggregates that can appear glassy, dull or even fibrous. The aggregate nodules often accompany many fine and rare minerals such as Apophyllite and Okenite plus many of the Zeolites. Looks very nice on blue green Prehnite! Would be a beautiful addition to any new or existing collection.

Gyrolite often forms nodular aggregates that can appear glassy, dull or even fiberous. The aggregate nodules often accompany many fine and rare minerals such as Apophyllite and Okenite plus many of the Zeolites. Looks very nice on Prehnite! 

Prehnite can form prismatic, tabular, or pyramidal crystals, but usually occurs in botryoidal, reniform, stalactitic, granular, or compact habits.  It is usually green in colour, but may be white, colourless, yellow, or gray.  It has a colourless streak.  Prehnite is transparent to translucent, with a vitreous to pearly luster.  Prehnite forms in cavities in basaltic lavas.

Apophyllite is a mineral belonging to the phyllosilicate group. It is known for its distinctive crystal formations, often occurring in clusters with a unique beauty.  Apophyllite crystals are usually colorless or white, allowing them to be transparent or translucent. Although, some specimens may exhibit a greenish, yellowish, or pinkish tint due to the presence of impurities. 

Apophyllite is believed to have a calming effect, and to effectively reduce stress, releasing mental blockages and negative thought patterns. Apophyllite is also said to release suppressed emotion, to overcome anxiety, worries and fears. It calms apprehensions and allows uncertainty to be tolerated.

Prehnite is said to be a stone of unconditional love and the crystal to heal the healer. Placing it in the garden is believed to help make a home into a healing sanctuary and teach one how to be in harmony with nature. A good Fung Shui stone, prehnite is said to be helpful for decluttering, helping one let go of possessions no longer needed.
