The EISCOSphalerite Specimen is a 1" (3cm) mineral sample, often mined as a zinc ore, making it an excellent educational tool for classroom labs. It features triboluminescence, allowing it to glow when fractured, and comes in a clear, labeled bag for optimal storage.

Perfect for studying geology
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 good size to see color and details. Thank you very much.

Larger than promised and very nice!
Nice specimen. Mine is over 1.25" long and 1" wide. Very sparkly, druzy. Looks like it's laced with pyrite. Came, as identified in a sealed plastic bag, identifying it as sphalerite. Very happy with this purchase. Thank you!
