Blue Sapphire-Cushion .94cts. This All American Sapphire® has been cut into a cushion shape that imitates the emerald shape but is much more brilliant than the conventional emerald cut. This stone displays a fine medium toned blue color in daylight that shifts to an agave or slight teal color in artificial light. Clarity is excellent and so this stone, in this shape, displays a brilliance not often associated with sapphires. This is a relatively inexpensive sapphire that will make a great center stone.
