The Gemstone Rhodochrosite

Banded Reddish-Pink Rhodochrosite

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.

All 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

? Banded Rhodochrosite is used as beads for bracelets and necklaces, and may also be cut and polished into cabochons. The rare and transparent deep-red form is very difficult to obtain, and is occasionally cut into a rare and exotic collectors gemstone
