More Rocks You Might Enjoy

Dolomite rock

When tumbled, the dolomite rock is smooth and glasslike. Often in shades of red, brown, or orange, they can also be grey or cream. Dolomite rock is found worldwide in sedimentary basins, but particularly Italy and Brazil. It was used as an ornamental embellishment by some Ancient Civilizations and is a collector’s item. Large material is decoratively carved.

Blue Chalcedony tumbled

Blue Chalcedony tumbled is a beautiful stone whose color can range from light blue to sky blue. The material is mined in Japan, Malawi, Namibia, Portugal, Romania, Turkey, and USA. Blue Chalcedony tumbled is often seen in the form of tumbled stones, but it's regularly cut into beads or carved and used with jewelry.

Orthoclase tumbled

Orthoclase tumbled is most often seen in hues of light brown or a grey-beige, but shades of red and white have also been found. The most important commercial deposits are mined in Russia, Tanzania, Italy, and the USA. Orthoclase tumbled is a collector’s gem and often made in to cabochons.

Fluor-uvite

A rare tourmaline found in conjunction with high quantities of boron, fluor-uvite has almost no practical use. It is largely sought by collectors who value it for its scarcity, color and (often) large crystals. Its name derives from Uva Province, Ceylon (now Sri Lanka), where it was first categorized in 1929.

Crackle Quartz tumbled

Crackle Quartz tumbled is valued for its ability to accept dye, resulting in transparent, bright stones with tiny sparkles. This type of artificially-made quartz is commonly found in the form of beads or tumbled stones. Though it's quite fragile, due to its sparkling appearance and rich coloration, it's a top-selling tumbled stone.
