A snakeskin agate key chain which really does look like a reptile skin pattern: a large crackle agate in browns with white between the veins. When you heat an agate and then dye it, you get crackle agate, sometimes called dragon vein agate. I have other pieces in my agate section as well. The rock is 5 cm (2 inches) long, attached to a handmade stainless steel chain, a small brown and white agate bead, and a 3.3 cm (1 1/4 inch) key ring. The total key chain length is 12.7 cm (over 5 inches). I used sterling silver wire to wrap the stone to the chain.
