Fiber optic glass is a man-made glass composed of millions of glass fibers that have been fused together into a block. 

This creates a reflective characteristic known as cats-eye. 

This material can be slabbed easily with a diamond blade. 

It is a great material for making cabochons as well as flint knapping into arrowheads, spears or other shapes.

 I will combine pieces together to get you the best shipping prices.

We have been selling rough rock and slabs in Quartzsite, Arizona for over 20 years.
