This is a matched pair (19 left 11 right) of gorgeous rare pink/purple and Black. Or not. I split this stone because as you can see it is gorgeous on both sides. It was a net wracking split that worked and that is very rare to be able to split Thomsonite. So that all said it can be a pair for earrings or two separate for ring/pendant combo
