Ahh, blue sea glass. Called the Sapphire of the sea. An elusive sea glass color, the color everyone wants to find, but few do. One thing I learned when I started working with sea glass is that a lot of the value of sea glass is based on rarity of color as well as how perfectly frosted and smoothed it is. Blue, especially dark cobalt blue, is one of the most coveted blue sea glass colors. It is said that 1 out of 300 pieces found will be cobalt blue sea glass.
This is an amazing piece of cobalt blue sea glass that was waiting for me on the beach. Beautifully smoothed. How lucky!
