Tiger s eye is a yellow and brown-banded gemstone, and Hawk s eye is similar but with blue bands. Both come from South Africa and result from silicification of cross-fiber veins of crocidolite. Cut en cabachon, and parallel to the fiber length. Tiger s eye and Hawk s eye exhibit variations in sheen and color that arise from the not-quite-parallel arrangement of the intimately associated asbestos and quartz. [Pg.78]

CROCIDOLITE (Blue Asbestos). The mineral crocidolilc may be considered as u fibrous variety of the monoclinic amphibole. riebeckile. Ii is also known as a massive mineral. Iis hardness is 4 specific gravity, 3.2-3.3 luster, silky to dull color, blue or bluish-green. It is found in Austria, France. Bolivia, the Republic of South Africa (the variety known as tiger s-eye) and in the United States, in Massachusetts and Rhode Island. The name crocidolile is derived from the Greek, meaning to weave, in reference to its fibrous appearance. See also Uat s-Eye. [Pg.451]

Whereas fibers of chrysotile resemble rolls of newspapers when viewed as a cross section of fibers, crocidolite is an amphibole and its fibers are laves with a trapezoidal cross section. As mentioned, this behavior is related to the cross-linked double chains of silicate from which these fibers are formed. Like [NaCa(P03)3]n which is grown as single crystals and must be milled to be converted to fibers, crocidolite is not a natural fiber as it is mined. It must be milled before it is cleaved to fibers. Unmilled crocidolite mineral is a beautiful stone known as either Cat s eye or Tiger s eye. It is also known as Riebeckite Asbestos. ... [Pg.104]
