We have both slabs and rough of Marra Mamba tiger eye. This material was mined out in the 1970’s. It is the most sought after form of tiger eye because of its mix of highly chatoyant tiger eye, (which can be golden, bluish, greenish or reddish), hematite and jasper. Finished stones are very popular. These Marra Mamba tiger eye slabs were cut many years ago and were recently brought out of our “archives”.
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.
