This pretty light blue-green Montana sapphire is completely natural and unheated. There are some inclusions in this stone, but they barely detract from the brilliance and are not easily visible at arms length. I have discounted this stone accordingly, making it a great value for its size.
This sapphire has been faceted in my own modified version of the diamond round brilliant cut, one that I’ve specifically optimized for sapphire to produce the desired “hearts and arrows” effect. The result is a scintillating gem, perfect for an engagement ring. It weighs 1.40 carats and measures 6.6 x 4.2 mm.
