This Sapphire is nothing short of gorgeous. What a brilliant fireball. The sapphire was cut by master faceter " Mike Soebbing. He cut it in a design called "tessellation 13" It is a all natural unheated Montana sapphire from the Eldorado bar sapphire mine. It is 8.75mm. X 6mm. And 2.39ct. This would make a one of a kind wedding ring or an irreplaceable fashion ring. Do not think this one will last long. Extremely rare color for us. It is super clean.
