Diamond marbles I first saw these on a trip to Antwerp many moons ago, made from what would once have been industrial quality rough, full of inclusions. Only about 40% of the crystal remains once sculpted into a sphere, so using cheap starting material is important, particularly since they have not been easy to market in jewellery. They would certainly survive the kind of brutal plays that were essential back in my playground marble playing days than the glass ones I has, that always ended up being slowly chipped to pieces.
