Members jimi Posted February 29, 2020 Members Report Posted February 29, 2020 Hi There, Maybe try a flat diamond stone? the ones you use for chisels?? Jimi. Quote
mikesc Posted February 29, 2020 Report Posted February 29, 2020 (edited) Diamond stone will do it..your Ruby blade is Aluminium Oxide..which is a wee bit less hard than diamond..I use diamond tools and files ( polishers etc ) to sculpt pieces of "Ruby".. Gemstone Rubies and Sapphires, Emeralds are just larger unflawed crystals..Jewellers use diamond stones and tools and diamond dust to facet and polish them. Edited February 29, 2020 by mikesc Quote
