The origins of sea glass can be traced back to discarded glass bottles, jars, and other glass items that have been thrown into the ocean. Over time, these items break down due to the constant motion of the water and the abrasive action of sand, creating the sea glass that is sought after by artisans and consumers alike. It is estimated that only about 1% of the glass that enters the ocean becomes sea glass, making it a rare and valuable material for jewelry.
