I also have fallen very much in love with the sapphire I'd chosen for an experimental ring. (This makes the experiment more problematic, since I hate to set it into a ring that almost surely will NOT be the best size for whoever falls in love with it...)
Anyway, this stone: it is a color change! meaning, that in many lights it's light green, but in others it looks like a citrine, with that yellow-golden-orange color. This is so cool! I'm going to ask J if, with his magical varying lightbox, he can get a picture of it in its different colors.
