Guitar Picks made of stone are quite rare and therefore there isn't much material on them.
The process of making a Guitar Pick out of a rock specimen is tedious and long, very much like the making of a cabochon which is a slice of rock cut to shape and polished by hand over and over again (10-15 stages of polishing) until it is mirror smooth and ready to be set inside a silver or gold frame to make a most special and beautiful looking piece of jewelry.
