A wonderful specimen for a collection. It is part of a large nut that has been dremelled to follow the little pools and lines of opal. Underneath is like the ironstone is all bubbly and molten. Could be used as an interesting paper weight for that special someone who has everything . Measures approx 76mm x 50mm x 30mm at longest, widest and thickest points. Weighs approx 155 grams.
