Pair of Medici vases in white marble, end of 18th century

Beautiful pair of Medici vases in white marble from the end of the 18th century.
The flared neck, molded on a smooth body ends on a godrooned base placed on a molded pedestal and square base.
There is an original addition perfectly cut and not broken at the base of the godroons of one of the vases (see photos)
The interiors are cut by hand.
Period late 18th century.
The vases were outside and are therefore weathered and natural.
NB: drilled for the flow of water and a vase measures half a centimeter higher than the other.
