I love finding one of a kind stones - because then I have to make one of a kind things with them. One of the joys of buying handmade is that each item is unique, but when you add in extra special free-form, one of a kind stones it makes them even more special. 

This ring is a size p1/2 (I could bump it up to a Q) 

The band is 1.5mm round profile. 

The pinky tourmaline is a freeform rose cut with a green band on one end, and I've set it in fine silver.
