Thulite gem stone

Another rose-red massive stone is furnished by the variety of zoisite, known as Thulite. This resembles rhodonite in color somewhat, but is easily distinguished by its chemical characters, zoisite being a hydrous silicate of calcium and aluminum. It is somewhat harder than rhodonite.
