Also commonly seen as Pietra Dura, Pietra Dure is the technique of using precision cut, highly polished rocks to create a painting in stone.
I’ve never seen this technique used by the “big names” in Victorian furniture but here is a paper-labeled Alexander Roux table up for sale at Nadeau’s Auction Gallery in Windsor, CT.
In the center of the decorative stones is a “micro mosaic” of a Roman Colisseum, which also appears to be made up of even smaller stones.
Bidding on the table ends today and begins at $12,500 with an expected range of $25,000 to $35,000. More images of the table and stone surface can be seen at the listing.
