Ethiopian Welo Opal and Snake Sterling Silver Ring

This sterling silver ring consists of a snake and a beautiful flashy ethiopian welo opal. It's stamped 925 on the back of the silver around the opal. Please keep in mind that the opal will look different depending on the lighting. I tried to capture it both indoors and outdoors to show how the lighting can affect the color. It does have some slight tarnish. Please see photos for size. Please keep in mind that crystals occur naturally, therefore they are not perfectly shaped.
