[QUOTE="Lefty, post: 174663, member: 2976"] mfdes, here's and article you might find interesting. [url]http://www.australiansapphire.com/sapphire_formation_theory.htm[/url] Like Jim, I've noticed differences between different parts of the same field. At our old claims just behind Rubyvale township, the sapphires were predominately blue and most of those were a bit dark, with a smaller proportion of greens and a few yellows and stars. About 10km away at the Washpool diggings, the stones are predominately green and i've only ever found a single blue up that end of the field. I've heard of places where (small) yellows make up around 50% of the stones and other spots where "fancy" stones turn up with some regularity. And this is all on the one field. I have seen lighter, sky-blue stones turn up on our field but the Thais seem to buy most of the best stones from our field. And then take them overseas and re-label them as Thai or Ceylon stones :mad: [/QUOTE]
