This auction a block of RED WHITE & BLUE Fiber Optic Glass.

It weighs 2.9 pounds. 

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.

We will combine shipping for auctions.

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