Mineral Specimen Size Information

On each crystal and mineral specimen you will see an acronym under the description of the product to give you an idea of the size of the piece. Generally, our photos do not give you a definite idea of the size specimen that it is, so these acronyms, as well as the photos posted below will give you a good reference point to the size of the mineral that you're looking at.
