High grade silver sheen obsidian from Mexico. Man I love obsidian and this silver sheen is definitely a unique variety! When held in the light, the silvery blue grey colors seem to move almost like the chatoyancy seen in tigers eye. We have some XL and thick slabs available which would be super fun to knap and would be great for knife making.
