This remarkable unheated sapphire is a beautiful rich, deep blue-green color. While this is a classic Montana color, it is very rare in an unheated sapphire and even more rare in one this large! It has excellent clarity, with just a tiny amount of natural rutile silk and a tiny crystal inclusion, neither of which are visible except with a 10x loupe. Very few Montana sapphires are large enough to facet a stone of this size; combined with the color and the fact that it is unheated/untreated, this is truly a rare and remarkable stone.
This sapphire is faceted in the classic diamond round brilliant design, cut to “hearts and arrows” precision. It weighs 3.11 carats and measures 8.5 x 5.7 mm. It would make an amazing center stone for a beautiful engagement ring!
