Colored diamonds often referred to as fancies are very rare. They come in a range of colors such as blue and pink - the yellow or canary color is especially prized. Our Diamondeau - flawless simulated diamond Canary stones simulate many of the qualities of D colored mined diamonds, such as cut and clarity plus they are both able to cut glass but without the huge cost and worry over insurance. Canary diamonds were a favorite of Wallis Simpson, Duchess of Windsor, and she would surely have approved of our stunning Canary ring.
