A beautiful teal blue-green Montana sapphire in a modified classic diamond round brilliant, 1.18 carats.

In stock


This beautiful unheated Montana sapphire is a typical color for Montana sapphires–a beautiful teal blue-green color.  This stone is very clean, with just a few tiny inclusions that are barely visible in this macro image, but not visible in the hand without a 10x 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 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 1.18 carats and measures 6.3 x 4.1 mm.
