All About

When used as a gemstone, Rhodonite is almost always opaque. A rare form of transparent gemmy Rhodonite is occasionally faceted as a gemstone, creating a deeply colored beautiful gemstone. This form of Rhodonite is relatively soft for a gemstone, and being highly valued by mineral collectors, it retains its value in its natual form. Thus, such stones are rarely cut, but when they are they command very high prices.

Rhodonite was used as an important carving stone in Russia, with classic ornamental pillars, serving bowls, tiles, and sculptures made from Rhodonite for Russian aristocrats, especially the Russian czars.

Uses

? Rhodonite is polished into beads and cabochons, and is used in necklaces, bracelets, and pendants. It is occasionally carved into ornamental objects, ornate tiles, and small statues. The deep pink to red transparent forms are occasionally faceted as rare gemstones.

Treatments & Enhancements

? Rhodonite gemstones are generally not treated or enhanced, although they may be occassionally waxed to enhance luster.

Rhodonite Sources

? Sources of gem Rhodonite are Russia, Australia, Japan, Madagascar, Sweden, Brazil, and Peru. Rhodonite also comes from the U.S. at New Jersey and Massachusetts.

Similar Gemstones

? Rhodochrosite is much softer and usually contains white banding, and Thulite lacks the black manganese oxide dendrites and inclusions.
