It’s tough to imagine that a mineral using a name as mundane as corundum yields gems as exquisite as the ruby and sapphire, or even that these two stones, so distinct in color and mystique, are truly the same mineral family.
Lucky you if your birthstone is sapphire (September) or ruby (July). These are among the richest-colored of all gemstones with a romance and history as colorful as they’re. Rubies are basically rarer than sapphires, and only red corundums are referred to as rubies. Any other color is really a sapphire. When grading colored stones, the density and hue on the color are part from the evaluation, and it is the richest, deepest colors which are one of the most prized. In rubies, the most prized variant of color is known as pigeon’s blood. Large gem top quality rubies might be much more valuable than comparably sized diamonds and are certainly rarer. There is usually a relative abundance of smaller, (1-3 carat,) blue sapphires compared for the scarcity of even little gem excellent rubies, making even these smaller stones relatively high in value.
Stones of Burmese origin generally command the highest prices. The vast majority of rubies are “native cut” from the country of origin. Higher value ruby rough is tightly controlled and rarely makes its method to custom cutters. Occasionally, such native stones are recut to custom proportions, albeit at a loss of weight and diameter. Custom cut and recut stones are usually much more per carat.
Sapphires exist in all the shades of blue from the deep blue of evening skies towards the bright and deep blue of a clear and stunning summer sky. Sapphires also come in a lot of other colors, not only from the transparent grayish misty blue of far horizons, but also displaying the bright fireworks of sunset colors – yellow, pink, orange and purple. So sapphires are really and truly heavenly stones, although they are being found inside challenging soil of our so-called “blue planet”.
