Rhodonite is a pink semi-precious stone crossed by black veins of manganese oxides. It is chosen for refined decorative surfaces with an unusual, delicate colour.
History and origin
It is a manganese silicate found in several deposits around the world, including historic sites in the Russian Urals. It has long been used for ornamental objects, small sculptures and inlays. In interior design it appears mainly in composite slabs and small formats, given its value. Marmi di Carrara supplies it on request.
Look and veining
The background is bright pink or pinkish red, with black networks and patches caused by manganese oxides. The ratio of pink to black varies greatly between pieces, from almost uniform areas to densely veined ones. Polishing intensifies the pink and gives depth to the contrast with the black.

FAQ
Are the black veins a defect?
No, they are manganese oxides typical of rhodonite and form its characteristic pattern.
Are there solid slabs?
Only in small sizes: for tops and walls, composite slabs are almost always used.
How does it differ from rhodochrosite?
Rhodochrosite is a carbonate, softer and with concentric pink bands, while rhodonite is a harder silicate with black veins.
