These Fordite Modern Blanks (also known as Detroit or Motor City agate) are incredibly rare! These blanks are from a modern 4 x 4 automotive plant and are extremely cool! Fordite is a buildup of old automotive paint that has been baked numerous times and hardened sufficiently to be cut and polished.
They are sized at 3/4 x 3/4 x 5". *Recommend using solid carbide to drill. (Priced per blank)
