[QUOTE="Dihusky, post: 469949, member: 10304"] Interesting, have always kept well away from modified ruby, Sapphire though I believe is far more accepted as heat treated? Do you know what temp your Sapphire examples were treated to, as I have read that this is fairly critical? From what I gather, rightly or wrongly, a temp of 1750C with a soak and slow cool produces the best results, but not many can afford a furnace that can do this, let alone get their money back on the investment when you add in electricity costs as well. :( Because of this, heat treatment to lower temperatures is common but produces poorer results??
