Oval Iridescent Shell Earrings

I recently acquired a collection of these large slivers of paua shell with intense color.  They weigh nothing and are ovals 1" x 3/4."  I created a simple bezel to show off their iridescence, and hung them from a sterling silver wire.  

Each pair will be unique as no two slivers are alike. I do my best to match them! Total length about 1 5/8."  Packaged in a reusable linen bag, ready for gift giving.
