Rhodochrosite as a Gemstone


Colorado Rhodochrosite crystals
Crystals of transparent red rhodochrosite on tetrahedrite with a few clear quartz crystals. This specimen is about 5 x 4 x 2 centimeters in size and was taken from the Sweet Home Mine. Crystals this transparent and of such wonderful color would make beautiful faceted stones, but because this is such a fine crystal specimen, there would be a huge financial loss if that were done.

Rhodochrosite is a favorite gemstone of many people. It is often slabbed to show off its banded or concentric patterns. Most of the slabs are used to cut cabochons.

Cutting rhodochrosite is a difficult job because the material has perfect cleavage, and it is so soft that it can be difficult to polish. Nice, stable, slabbed material is sometimes used to make small boxes and other ornaments. The rare transparent material that is not suitable as a mineral specimen is sometimes faceted into attractive pink and red gems. The beautiful stones produced are mainly for collectors because faceted rhodochrosite is too fragile for almost any jewelry use.

Rhodochrosite has a hardness of only 3.5 to 4 and has perfect cleavage in three directions. This eliminates it as a good choice as a ring or bracelet stone which might be subject to abrasion or impact. It is better suited in earrings, pins, and pendants, which are generally not subject to as much abuse as a ring.
