In stock


This lovely Montana sapphire is pleasing shade of medium blue, with just a hint of green to it.  This particular sapphire has been heated to develop this color and improve the clarity.  The treatment is permanent and stable.  There are some tiny internal inclusions just barely visible in the macro image, but they are not visible in the hand without a loupe–its an eye clean gemstone.

This sapphire has been faceted in my own modified version of the diamond round brilliant cut, one that I’ve optimized for sapphire.  The result is a beautiful gem, perfect for an engagement ring.  It weighs 1.12 carats and measures 5.8 x 4.3 mm.
