This pendant is a peice of sea glass from Seaham in Co.Durham. Over 100 years ago in Victoria times, there were 7 or so glass factories in Seaham. They used to dump scrap glass in at the end of the day. For over 100 years this has been tumbled and fashioned by mother nature. 
This pendant is approx  25 x 12 mm and embellished with a sterling silver wire charm. It is set on a beautiful 18 inch sterling silver box chain. 
Sent gift boxed.
