[QUOTE="Lefty, post: 286869, member: 2976"] It's true that sapphires have a high specific gravity and tend to settle because of this but as already mentioned, they can be anywhere from right on the surface to half way to China, regardless of their size. I saw a beautiful yellow-green parti just under 50 carats that was found right on the surface. The Black Star of Queensland is nearly the size of a hen's egg and it was found on the surface. Absolutely! If it's a nice, reasonably clean stone with a good shape and not dark I certainly wouldn't turn my nose up at a 5 carat one. It could easily facet a nice stone of a carat or perhaps more.
