This stone is from Montana USA and weighs 1.79 carats, measuring 6.96mm in the shortest dimension and 7.34mm across the corners. This stone has a steely, slightly greenish blue color in outside light and getting a bit more steely under fluorescent lighting. This stone is slightly included, as is most Montana sapphire, but these inclusions are very hard to see. This would make an excellent ring stone for those who like the look of Aquamarine, but want something more durable . At under $150 per carat this is a very good deal, but I'm always open to offers, particularly if I can provide the setting for this.
