Rhodochrosite has a lovely natural pink to red color. Rhodochrosite gemstones are primarily translucent to opaque banded beads and cabochons. These bands are often in concentric or zigzag patterns of alternating white and pink (or red) colors. The transparent red forms large enough to be cut into gemstones are extremely valuable and cherished by rare gemstone connoisseurs.

About

Though Rhodochrosite has a very pretty color, it is not a durable gemstone because of its low hardness. It is easily scratched, and care must be ensured to preserve it. Much of the banded form of Rhodochrosite comes from Argentina, where the Rhodochrosite forms as stalagmites and stalactites in ancient Inca Silver mines and caves.

Uses
