Sea Glass Color Rarities

Sea glass can be found on beaches all around the world and come in a variety of colors. The color of the glass determines how rare it is and gives us some history on its origins. Common colors of sea glass, such as brown and white, make up a majority of the sea glass found. These colors originate mostly from beer and liquor bottles. Studies show that up to 60% of all sea glass found are these two colors. Colors such as orange and red on the other hand are much harder to find. Orange in particular only accounts for 1 in 10,000 pieces found. With this being said, if you find one of these rare pieces you are one lucky person. Other rare colors such as sea foam and cobalt blue can be commonly seen on our rare sea glass jewelry page. Sea foam originates primarily from old Coca Cola bottles and cobalt originates from old medicine bottles. In our opinion, these shades of blue are most beautiful and make for the best jewelry pieces. Check out the rare sea glass jewelry that we have sold here. Below we have a list of sea glass color rarities and some of their possible origins.
