Hello,
MST-Müller is selling "Original Thuringian Waterstones". Some claim that they are near to the Eschers, but not as good. I donīt know, i donīt have one. Unfortunately, they have only small stones, but now, they have artificial Stones, which they claim to have similar properties:
0riginal
I donīt have one and i donīt want to buy one, being addicted to natural stones, but perhaps someone of you is interested in it
Regards,
tok
