Montana Yogo Sapphire Jewelry

People often ask what is the difference between a yogo sapphire and a Montana sapphire. Yogo sapphires were mined near Utica Montana at Yogo Gulch sapphire mine.  Yogos are usually cornflower blue or purple and are not heat treated, this is a natural sapphire.  Yogos are usually very small because of the way they formed the rough is fairly flat. Yogo sapphires are Montana sapphires but Montana sapphires are not always Yogos.  Our other Montana sapphires are from either Rock Creek or the Missouri River here in Montana and are usually larger and do come in all the colors of the rainbow.   Although  all Montana sapphires are rare and are no longer commercially mined, Yogos are the rarest and are famous for their Yogo sapphire cornflower blue color and their place among the Crown Jewels of England.
Because of their hardness, Montana Yogo sapphire engagement rings are very popular.
Montana Yogo sapphires are always natural in color and never heat treated.
