This impressively bulbous, frosty dark honey brown sea glass piece is 2 cm long. It was found on a beach along England's North Sea. It is very well frosted and smooth all over with a nice flat back, which makes it optimum for a jewelry pendant. US dime in last photo for size reference.
Your genuine sea glass will come with a display card that tells the short story of sea glass and the name of the ocean where it was found.
