This authentic sea glass and Jasper necklace has unisex styling and can be worn by either guys or gals. It is made with four pieces of Northern California sea glass, two white and two light blue. It features a focal polished gray Montana Jasper stone. All strung on a 20" inches long black braided faux leather necklace with a lobster claw clasp and 3" inches of sterling chain. This allows for varied sizing. The sea glass and stone charms lay approximately 1" by 1 3/4" inches with copper findings. My By the Sea jewelry collection is inspired by the ocean. This necklace is perfect for the man or woman who loves nature and loves the ocean.
