A carved white marble and Blue John inlaid urn on stand, after the Antique probably English, late 19th century

with a knopped lid above an inlaid fluted and gadrooned bowl on a waisted stem above a black and white marble stand with applied disc motif

Very decorative. Could easily be Italian or English. Surface with ingrained dirt could do with a clean. The body of the vase appears to be late 18th century English but the stem down to the plinth all looks a recent replacement.
