1.50-Carat Aqua Blue Montana Sapphire (Heated)

1.50-Carat Aqua Blue Montana Sapphire (Heated)


A lovely aqua blue heated Montana sapphire faceted in my custom “Testudo” brilliant oval design, 1.50 carats.

Out of stock


This gorgeous heated Montana sapphire is a lovely aqua blue that reminds me of the tropical waters of the Caribbean. The sapphire has very good clarity, with just a few tiny inclusions too small to see without a 10x loupe. The high clarity makes it a very bright and scintillating gemstone in person.

This sapphire is faceted in my custom “Testudo” brilliant oval design. The gem weighs 1.50 carats and measures 7.6 x 5.8 x 4.5 mm.  It would make a unique and eye-catching center stone for an engagement ring.
