Sea glass is smooth, weathered glass that has been naturally polished by the ocean. It originates from broken bottles, jars, and other glass items that have been discarded into the sea. Over time, the waves and sand wear down the sharp edges, creating small, colorful pieces that can be found along beaches. Collectors often seek out sea glass for its beauty and uniqueness. The colors can vary widely, including shades of green, blue, brown, and rare colors like red or purple. Many people use sea glass in jewelry, art, and home decor, celebrating its natural transformation.
