1.89-Carat Sky Blue Montana Sapphire

1.89-Carat Sky Blue Montana Sapphire



A beautiful sky blue unheated sapphire from Montana, 1.89 carats.

In stock


This lovely unheated sapphire is a beautiful sky blue color, like the “big skies” of Montana.  The gem has excellent clarity, with just one small feather and a tiny amount of silk.  Because of the orientation and size of the feather, it is very difficult to see face up without a loupe; it faces up as an eye-clean gemstone.  I have factored it into the pricing, making this an excellent value for the size and color.

This sapphire is faceted in the classic diamond round brilliant design, optimized for sapphire and cut to “hearts and arrows” precision.  It weighs 1.89 carats and measures 7.3 x 4.8 mm.  It would make an amazing center stone for a beautiful engagement ring!
