Seaham used to be home to Londonderry Bottleworks, the largest glass factory in the UK. And for roughly 80 years, the factory used to dump leftover and waste glass into the North Sea.
To this day, loads of sea glass wash up with every tidal shift, including multi-colored pieces. The neat thing is that since the factory closed down in the early 1920s, there's a pretty good bet that Seaham glass has been tumbling around in the ocean for a century or more.
Pretty cool, huh?
This pendant features two pieces of Seaham sea glass, with an "open back" so you can see the front and back surfaces of both pieces of sea glass. The bezels are linked together with an artistic flourish, just to keep it interesting.
