These are individually wrapped minerals picked from across our range of rocks. If you want a little treat for yourself, this piece of rock mail will perk you up. 
Buy one mystery crystal and I will pick it out and post it to you. Pick more than one mystery mineral and I will *try* to make sure you don't have any doublers before I send them.
