Your cart is empty. Raw Gypsum Specimen
Set of 6 Samples, 1"
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 1" in length. Set is packaged in a transparent bag, labeled & barcoded for easy identification and storage.
Selected & Processed by a Geologist.
Each and every specimen is selected and hand processed by an actual geologist, ensuring that each sample exhibits defining features. Rocks and minerals are sourced from a variety of locations around the world and are processed by hand in Victor, NY.

I use these rocks for my geology classes. When very small items are sent it is impossible to learn anything from examining the specimen. The larger (1 1/2 and up) are perfect. The rocks I received from this seller are perfect. A great assortment of sizes, shapes, and variants. Perfect for studying geology.
