    Only problem is slate is not sedimentary its metamorphic. It starts as shale which is sedimentary and once its metamorphosed all those particales are further packed down and reduced to form the slate. Slate is very heavy dense stuff. If there were garnet xtls in the slate I would think they would be very deformed or made different by the heat and pressure. Usually when garnet is metamorphosed it becomes a different mineral the name escapes me, maybe garnierite but its usually massive stuff no xtls.

    There is a Beryl Hone on ebay right now, the seller is claiming it to be equivalent to 8k Natural Beryl Polishing Stone Graver Sharpening Tool - eBay (item 120446717540 end time Aug-09-09 20:41:49 PDT) Was thinking of ordering one for myself, but I think it may be a bit narrow for my personal taste.

    Kindest regards,
    Alex

    Well ruby is just corundum which is aluminum oxide so whether its ruby or sappire or common alumina the effect is the same. Most commercial "ruby" is really common alumina opaque and tinged pink so technically its ruby but practically its not. They also can do synthetic xtls too.
