Handmade from genuine sea glass from Lithuania and set with stainless steel components. Stainless steel is a great alternative to sterling silver. It will never tarnish, it’s durable and less expensive than sterling silver. Cobalt blue is the richest of color in my opinion when it comes to sea glass. Want a custom order?
