What is your Unicorn piece?
A Unicorn piece for various collections is one that is extremely rare to the point one may question weather or not they exist. What is yours? What is Unicorn of each collectible set you have? For me, in both my Kiwi Jasper and yellow banded calcite (YBC) it is a slab. It's a long rectangle about half a cm thick, long and ranges in height. It's like A for some crystals depending on how they grow or like B when its cut from a large piece. **Neither photo is mine. Examples from the internet**
