This Montana sapphire is a pretty light pastel violet to blue violet; the color shifts with the lighting. This gem is natural and has not been heated or treated in any way. There is a little bit of silk in the stone that cuts back a little bit on the brilliance–but the stone is far more beautiful and flashy in the hand than the photos imply. I faceted this sapphire in a custom square cushion design optimized for sapphire. The result is a brilliant gem weighing 0.90 carats and measuring 4.82 x 4.82 x 4.06 mm.
