Most items began life as bottles, jars, plates, home windows, or different glass objects that ended up within the ocean — by means of dumping, shipwrecks, coastal erosion, or just being swept off a seashore throughout a storm.
Over years — generally many years — the ocean rolls these shards throughout rocks and sand. The sharp edges put on away. The shiny floor turns into cloudy and textured, like frosted glass. What started as a hazard turns into one thing fully totally different: easy, tactile, and exquisite.
Sea glass is usually referred to as “mermaid’s tears” or “ocean gems.” It’s collected, displayed, and set into jewellery. It is usually, at its origin, a chunk of marine particles — a indisputable fact that provides a layer of historical past to each piece you discover.
