The tourmaline is mostly pink, with a rim of green on one side. The pink closest to the green is more saturated, and gets slightly lighter towards the side opposite the green. 

Stone is set in fine and sterling silver. Wide band is sterling silver.

Apx size is 6.5 with wide band. Keep in mind with wide bands you want to size up. This will more comfortably fit a size 6 - 6 1/4.
