This gorgeous amethyst ring is actually one of the many eco friendly rings available at Turtle Love Committee. This is a wedding band set where the amethyst is actually a unique take on an engagement ring. The two fit together perfectly up against each other, with the wedding band having an indent for the solitare. Eco Friendly Wedding Rings? Amazing! Get this eco friendly wedding ring set @ Turtle Love Committe. More eco friendly rings that we love are the Beer and Soda Pop Rings. I personally love the Little Pebble eco friendly rings that are also stacking rings.
