Thick agate trivet

I am selling this one-of-a-kind agate slab trivet. 1" thick of solid white agate with natural crystal pattern. 8" long (at its longest) and 7" wide (at its widest). Irregular oblong oval shape. Polished top. Weighs approximately 3.5 pounds. Has six small clear rubber feet to rest on table or countertop. Makes a unique charcuterie board, sushi platter, or cheese tray!
