Kees,
Under a microscope at 30 to 60x both do appear to have garnets as the cutting agent. I will confirm with the quarry tomorrow.

The first shipment will be 2x8 and 3x10 stones retailing somwhere around $60 for the smaller, $95 for the larger depending of fees when they land. Yes, Manufactum is Germany is cheaper but shipping on a single stone is the same or higher than the stone price alone. If you are in Europe buying directly from a source they will be advantageous and I can furnish info on how to buy larger stones for customers there. I am their USA distributor so shipping back to Europe again will not be the best idea <g>.
