Sea glass from California. One 925 Sterling silver box chain drop single earring with a rare, one-of-a-kind piece pale lavender sea glass🧜🏻‍♀️ Lavender sea glass is hard to find. It’s very old glass. It starts out clear or white and due to the manganese content and UV exposure, it turns various shades of purple. In the old days manganese was added to glass as a clarifying agent, and manganese turns purple when exposed to UV rays – like those in sunlight. The purple sea glass is also known as “sun” glass. My sea glass is ocean-tumbled, imperfectly shaped by the sea and hand collected. Handmade 🧜🏻‍♀️ ✈️FREE US SHIPPING✈️
