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.
This material is easily knappable and behaves like glass.
We have been selling rough rock and slabs in Quartzsite, Arizona for over 20 years.
