Marble set

Open this box, and you'll see a velvet-covered inside, holding a set of marble chess pieces.

The set didn't come with a board, so to set it up for pictures, I used the board I also used for my Matador & Flamenco set

As you might expect, the pieces are quite heavy for their size.

I know nothing more about this set, where and when it was made, etc. So if anyone has any further information as to its origins ...
