Aramis Antiques has dated this piece to the 1880s.
Being gilt swept, the pattern is not a uniform flat gold, which would not be pleasing. The method used conforms with the moving fluidity of the lines. Various themes can be seen with the design - an acanthus, swans and water and reeds at base. Hand blown glass probably from a Stourbridge factory. Absolutely stunning colour.
