Genuine sea glass earrings in cobalt blue, dangling mermaid's tears on sterling silver posts. The ocean was into repurposing long before it was trendy; sea glass comes from human garbage that is surf tumbled until it becomes smooth & frosted. Cobalt blue is not a common colour, and it is hard to get two pieces that match well enough for earrings - fortunately, you are in luck here! The glass hangs about 2.3 cm (nearly 1 inch) from the sterling silver studs. Each piece of glass is around 18-19 mm long (under 4/5 of an inch). A bit bigger than dainty, but not huge, and very lightweight. The backs are shown in the last photo. Sterling ear hooks and surgical steel hooks are also available, if you don’t want the posts.
