Silver Turquoise and Orange Gemstone Rings

I have these two rings that I cannot wear. They are not real silver and turn my finger green. But if you do not have that problem, they would be a great buy for only $18 for the pair. The first one in a turquoise and orange coloring features an eagle design. The second one has a turquoise like gem stone in silver with black etched feathers running down the side.
