1.60-Carat Light Sky Blue Montana Sapphire


A beautiful unheated light sky blue Montana sapphire, 1.60 carats.

Out of stock


This beautiful all-natural Montana sapphire is beautiful light sky blue color.  In daylight the color intensifies slightly while under incandescent light it can take a lighter more silvery-blue color.  Under some fluorescent lighting the blue becomes slightly more saturated in appearance, as in the primary photo here, which was taken under studio fluorescent lights.  The gem is remarkably clean for a natural unheated sapphire, with just one tiny crystal inclusion with a partial discoid around it.  Its tucked off to one side and perpendicular to the table, so its very hard to see even with a 10x loupe.  The gem is otherwise flawless and incredibly brilliant.

I faceted this sapphire in a brand new square cushion design that I’ve optimized for sapphire; the result is a glittering beauty of a gemstone. The design is named “Bella,” which is derived from the Latin term for beauty.  The gem weighs 1.60 carats and measures 5.7 x 4.9 mm; the perfect size for an engagement ring.
