Blue Sapphire-Round 1.24cts. This sapphire displays the best medium blue color in daylight that Montana has to offer. In artificial light the color shifts to a faint teal. The stone is eye clean in the face up position. Inclusions do not affect the overall appearance. Brilliance is maximized with the round brilliant shape. The cut quality is reflected in the diamond hearts and arrows profile which is the standard for the All American Sapphire®.
