5.06ct Dark Blue Montana Sapphire Cushion
This is an exceptionally large one-of-a-kind Montana Sapphire weighing 5.06 carats, a rarity to find. Measuring approximately 11 x 9mm, this cushion cut gem boasts a deep, rich, pure blue color that photos cannot do justice. It is loupe clean, another rarity for this size, and has been treated with heat-only. When viewed with a 10x loupe, you can observe some of the crystal growth lines inside the stone at just the right angle – a remarkable element that only adds to its beauty.
