0.43-Carat Pale Aqua Montana Sapphire

A beautiful light aqua blue-green unheated Montana sapphire in a modified classic diamond round brilliant, 0.43 carats.

In stock


This pretty little unheated Montana sapphire is a typical color for Montana sapphires–a very light aqua blue-green.  The macro image is like the view through a 10x loupe and shows a few small inclusions, but they are impossible to see in the hand without a 10x loupe.  In the hand the gemstone is very bright and lively and eye clean.

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 0.43 carats and measures 4.6 x 3.0 mm.
