A multi-layer gypsum specimen, whose life appears to have begun as a series of nearly colorless, translucent to transparent gypsum blades reaching 4.3 cm. These first generation crystals are contacted on the base (where growth started) and terminated at the tops. As the water level fluctuated and/or the dissolve gypsum concentration changed and/or the temperature changed, a thin layer of small but abundant gypsum crystals were laid down. Sometime later, another thin gypsum layer was laid down. This specimen is in superb condition (considering the mineral's softness and tendency to bruise and cleave) and displays very nicely. Ex Trinity Mineral Company; a note on the back of the previous dealer label gives a purchase date of December 1999 and a purchase price of $50.
