Polished Kambaba Jasper Cabochon - Choose your quantity! Uniqueness Guaranteed: Every item is one-of-a-kind, making them ideal for all projects or designs. Avg Size Range: (1 to 1.75 Inches Long) Kambaba jasper is not a true jasper, and is instead a variety of porphyritic rhyolite, a volcanic rock that contains larger inclusions in a fine-grained stone. The bulk of kambaba jasper is green, consisting of aegirine and albite with small inclusions of potassium-based feldspar, and the round black inclusions are riebeckite. Due to its resemblance to the animal skin, kambaba jasper is sometimes also called crocodile jasper. Handmade items vary in size, shape, and color when selected randomly (the highest quality items are chosen first). They'll be as beautiful as those in the photos.
