Sea glass surface (macro). Sea Glass Surface Magic The smooth, frosted texture you see on sea glass isn't actually from the ocean itself—it's created by billions of microscopic collisions with sand and rocks that essentially sandblast the glass for 7-10 years, the same way a jeweler polishes gemstones. Under a magnifying glass, you'll notice the surface has a crystalline pattern of tiny pits and ridges that scatter light instead of reflecting it, which is why sea glass glows that magical frosted white or soft blue color instead of looking like clear glass.
