This is a nice piece of natural Botryoidal Calcite with druzy pockets. The spiderling is natural Tree Agate and the accent is a 3-D printed and hand painted rams skull (not naturally sourced). This display measures 4 inches long, 3.5 inches wide and 2.75 inches tall and weighs almost 1 pound.
Each one of these display pieces is one of a kind but if you want to create one from scratch we can play with colors and spiders to make some that is unique to you.
