3.70-Carat Purple-Pink Montana Sapphire


A beautiful purple-pink unheated sapphire from Montana, 3.70 carats.

Out of stock


This beautiful unheated sapphire is a gorgeous purple color, mixed with flashes of a pink or magenta-purple.  Under indoor incandescent lighting, the color shifts to uniform rich magenta-purple.  I left a tiny natural near the girdle edge in order to keep this gem exactly 9 mm; it is very hard to see and can be hidden under a prong when the gem is set. This gem has very good clarity, with only a tiny amount of natural rutile silk present and one or two tiny inclusions only visible with a 10x loupe.  The high clarity gives the gem excellent brilliance–this is really a remarkable natural sapphire!

This sapphire is faceted in the classic diamond round brilliant design, optimized for sapphire and cut to “hearts and arrows” precision.  It weighs 3.70 carats and measures 9.0 x 6.1 mm–very large for a Montana sapphire.  It would make an amazing center stone for a beautiful engagement ring!
