About Sea Glass

Sea glass is man-made glass that has been worn down by the ocean over many years. Sea Glass Necklaces 1Sea glass begins its journey as a discarded piece of glass that finds it way into the ocean. It could be from a drunken sailor that threw his empty whisky bottle into the water while at sea. Or perhaps it could be from a glass fishing-bob that found its way overseas from japan. With sea glass requiring a minimum of 25 years to make, with some pieces taking up to hundreds of years,the possibilities of origin are endless. Once in the ocean this glass is broken down by the oceans powerful waves turning it into dozens of pieces. These small pieces of glass are then worn down by the movement of the sand smoothing out all of the sharp edges. In addition, the PH of the oceans water is just high enough to slowly dissolve the glass giving it a frosted look. The end result is a perfectly rounded and frosted piece of glass that resembles a semi precious gem. Sea Glass Necklaces 2The end quality of the glass is not only determined by how long it has been in the water, but also the type of sand it has been surrounded by. Pristine, jewelry-quality sea glass needs to be surrounded by fine powdery sand. This type of sand gives it a nice smooth texture. If the sand is too course it will scratch the glass, giving it a rough pitted finish. In addition to sand, large rocks can chip the sea glass making it unusable. Many times we have found a perfect piece of sea glass, only to realize a chunk is missing. Sea glass is rare to find, especially jewelry-quality pieces which must be free of flaws. On top of that, some colors are much harder to find than others. Brown and white, for instance, are the most common sea glass colors. I would say about 70% of all the sea glass we find are these colors with the other 25% being green. The last 5% are rare finds such as blues and even in some cases purples and oranges. Cobalt glass for example is extremely rare with a 1 in 200 chance of finding one. You can read more about rarity and where the different colors come from on our sea glass rarity page.
