Well, a number of years ago, in a mining district of India called Padparadsha, they used to find a really intense reddish orange Sapphire.  You'll still see one occasionaly come out of there, but every one I've ever seen had ugly written all over it -- cloudy, cracked, oxidized and weathered.  In fact, I've never ever seen a good one, but I hear the older guys talk about them with reverence -- it was apparantly a spectacular stone.
