This ring is made with a beach rock/ pebble from a beach south of San Francisco, where the surfer have lots of fun. The gray rock is the same way it was on the beach and will probably get a little darker with time. Inside I have inlaided a peridot in one of my favorite shape.
This ring is sold. Please email to have a custom one fabricated at your size.Will email photo of few pebbles for you to chose from. Thanks for checking my work.
