Cobalt Deep Sea Glass Bottle Lip Necklace

(No reviews yet) Write a Review

This gorgeous necklace features a uniquely frosted piece of authentic sea glass with a deep cobalt blue hue. An embossed horizontal line runs vertically across the sea glass's surface which is evidence of its former life as the lip of a glass bottle. This sea glass piece has a distinct organic shape that has been finely preserved in sleek sterling silver. The pendant has an open back design to allow light to shine through and highlight the natural color and beauty of the sea glass. Due to its age, the surface of the sea glass has a few very tiny "c" shaped markings. These markings are a characteristic feature of authentic sea glass that form naturally as the surface of the sea glass is hydrated by the ocean over time. The necklace is shown here finished on a sleek sterling silver snake style chain. Use the drop-down menu above to select your desired chain length or choose to purchase the pendant alone.

Please remember, ALL of our sea glass is genuine, ocean-tumbled sea glass that is collected on beautiful beaches in Massachusetts, California, Hawaii and the West Coast. It is NEVER machine-tumbled. Working with authentic sea glass presents many wonderful rewards! Each piece of sea glass is one-of-a-kind, making the jewelry truly unique! Each piece of sea glass is carefully selected for each design by color, shape and size. Earrings are sorted by hand and precisely matched up. LOTS of love, time and care goes into the creation of each piece from start to finish. We use only jewelry-grade, A+ quality sea glass that is smooth, beautiful and resembles a gemstone. Using only the finest of materials ensures quality and durability. We hope you will treasure the jewelry as much as we treasure the art of making it!
