Product Overview
A sulfate mineral that often forms from evaporating lakes in what is known as an evaporite deposit. Crystals grow into soft, wide sheets, but gypsum is also commonly found filling veins and fractures in other rocks. Ideal for identification & classification exercises. Gypsum's perpendicular planes of cleavages make it an excellent tool for studying 2-plane, 90° cleavage. While each specimen will vary slightly in shape, size and color, it will measure approximately 3" in length. Each is individually packaged, labeled & barcoded for easy identification and storage.
