Make four slices of a geode with this reusable silicone coaster mold.  The scalloped edging helps to recreate a geode look.  Add rocks, glass bits or something similar to help accentuate the edge.

Each slice measures 4 inches on the straight sides and 1/4 inch deep.

Great for making matched resin coaster sets to gift or sell!
