Pair of Portor marble bookends, black and golden yellow

Pair of bookends in portor marble, black and golden yellow. This marble is famous for the richness of its yellow-gold veins, and by the intensity of its black background, rich in organic matter and often traversed by tension slits filled with white sparite, it is relatively rare. In good general condition, scratches of use, micro-splinters at the edges, small repairs.
