Cobalt Ocean Deep Ultra Rare Sea Glass Trinity Drop Necklace

(No reviews yet) Write a Review

This lovely necklace features an ultra-rare piece of authentic beach-found sea glass, with streaks of deep and striking cobalt running across the surface of a crisp white background. Polished by the waves into a gorgeous oval shape, the smooth edges of this sea glass piece has been skillfully preserved in sterling silver with an open-back design to allow light to shine through and accentuate its contrasting hues. A few tiny "c" shaped markings grace the surface of the sea glass which form naturally as its surface is hydrated by the ocean over time. These markings are a characteristic feature of authentic sea glass. It then rests at the center of a sleek sterling silver teardrop outline with three shimmering silver beads resting beneath it. This charming necklace is shown here finished with a sleek sterling silver stardust-style chain. Use the drop-down menu above to select your desired chain length or choose to purchase the pendant alone. 

REMEMBER:  This is the EXACT piece you will receive!

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!
