Intricately chaotic aragonite cluster mineral rock / crystal specimen from Morocco
With the formula CaCO3, it is similar to calcite, but has a different crystal lattice structure
The othrhombic shape of the crystals looks nearly hexagonal due to twinning
Looks rusty: minerals that have an orange red, or brown color are often that way due to iron oxide impurities
15.83 grams, approximately 1.25 inches long x 1 inch wide
A great gift for your favorite geology lover, or a wonderful addition to your own rock collection!
The specimen in the photos is the exact one you will receive.
