This beautiful unheated Montana sapphire is a gorgeous aqua blue, bringing to mind the tropical waters of the Caribbean Sea. The gem is 100 percent natural and untreated in any way. The sapphire has excellent clarity and a hazy quality due to undissolved rutile silk. There may be tiny inclusions that are visible with a 10x loupe that can’t be seen with the naked eye.
This sapphire is faceted in my custom “Testudo” brilliant oval design that I’ve created and optimized for sapphire. The result is a glittering beauty of a gemstone. The gem weighs 2.55 carats and measures 8.8 x 6.6 x 5.5 mm; the perfect size for an engagement ring.
