aquamarine

Aquamarine, a name given to some of the finest varieties of beryl of a sea-green or blue colour.

The blue varieties are absurdly called oriental aquamarine by lapidaries.

The other type is the more familiar aquamarine window glass still to be found in 18th-century houses.

A piece of a bullseye pane of aquamarine glass occurs in the Marlborough finds.

She was in extremely low evening-dress of an aquamarine shade, flowered with gold.
