[QUOTE="Mr Magoo, post: 84978, member: 3008"] It's actually a lot more complicated than that. For the pink sapphire or Ruby argument a decision was apparently made (by the international coloured gem association) that pink is a shade of red therefore they could be called a ruby or a pink sapphire. That was in the late 80's, so could of changed since then. :rolleyes: The trouble is due to modern 'cooking' technique's red can also be brought out of the corundum without Chromium. So should the definition of Ruby be based on it's shade/tone of red or it's Chromium content? Anybody bought a nice Songea ruby lately? Or a Sunset Ruby (Game of stones). Now it's getting complicated and leads to confusion. :lol: :lol: [img]https://www.prospectingaustralia.com/forum/img/member-images/3008/1403491714_bidiff.jpg[/img] Now that is $18K of nastiness. (note the 'Bedif' in the description) (Oooopps drifted off topic again). Mr Magoo [/QUOTE]
