A natural labradorite faceted oval is fixed upon a 20 gauge sterling silver wire. If you catch it at the right angle you may catch the brilliant peach flash.

Ring starts at size 7 1/4, and is somewhat adjustable.  It is meant to fix to a size and be left there, adjustment may require tools.  Too much bending can break silver wire.

Labradorite is about 15x12mm.
