Vicky Thomas Antiques has dated this Antique Marble Tazza Pair to the 1900s.
Each dish sits upon a sounded column with gilded brass mounts, and has crossbanded detail, where the grain of the marble is accentuated.

Each pedestal stands on three brass feet and is 23cm high, the bowls measuring 13cm in diameter. There are a few nibbles to the rims, and a loss to the base of one ( all included in the photographs), but as you will see from the pictures are not particularly visible, and both display beautifully.
Please don't hesitate to get in touch if I can provide any further information or photographs. I offer free postage to the UK, and can help with quotes for shipping abroad.
