Earrings Natural Big Shell

Earrings: Natural shell earrings. A world traveling Healer gave me these shells and I converted them to earrings. I do not know the name of the shell but they are breathtaking! They are light as a feather and the post is 14 karat gold filled. The colors change from pinks to gold to greens with black, grey and brown...as the light hits it. They are 2 and 1/2 inches long and 2 inches wide. They felt magical when I tried them on.
