Landscape Tiger Eye Rough from South Africa - $7.50/lb
Tiger Eye has long been considered a quartz replacement of asbestos, otherwise known as a pseudomorph. The asbestos is gone, so it’s harmless to cut. However, new research into the origins of tiger eye shows tiger eye is actually not a pseudomorph. The fibrous structure of tiger eye creates chatoyance and also gives it a definite grain structure. So, you have to be careful that it doesn’t tear out when grinding and polishing. Polish with cerium oxide, tin oxide, or diamond. I prefer diamond for polishing tiger eye. Mohs hardness 7.
