Wedgwood Basalt Plate

This is a rare plate made from basalt by Wedgwood in the late 18th century though I am not sure when exactly. It is very nicely made with a neat relief pattern to the rim of possible arcanthus leaves. The plate is in perfect condition. It is marked underneath with the impressed WEDGWOOD mark and a star above that. Also what appears to be an impressed or incised A though it is a bit hard to make out. The piece is 0.625 inches tall and 7.75 inches in diameter. Please email me for more information or other pictures.
