This unique sea glass piece has a smooth flat shape. It features the rarest sea glass in a deep amberina. Amberina is a type of two-toned glassware, which was originally made from 1883 to about 1900.

England's North Sea has tumbled this piece into a flawless, pristine gem. It measures just over 2.3cm at its longest length. US dime in photo #3 for size reference. The historical relic was beachcombed after spending many decades in the surf being shaped and conditioned.

It will arrive with a card that tells the short story of sea glass and the name of the ocean where it was beachcombed.
