The Gemstone 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.
