Sapphire Elegance

September's gorgeous birthstone is the sapphire. While this luxe stone is best known for its rich blue hues, sapphires come in a full rainbow of colors. Sapphires are sought after for their hardness and durability, which is second only to diamonds. Read on to learn more about this gorgeous gemstone!

Color is the most important factor to consider when choosing a sapphire. The most highly valued blue sapphires are deep blue to violet-blue, in medium to medium-dark tones. An ideal sapphire should have vivid color saturation. The intensity of sapphire's color should be as strong as possible without darkening the color and compromising brightness of the stone. 

Clarity refers to the inclusions within a stone. Blue sapphires often have some inclusions; those with extremely high clarity are rare, and very valuable. Price can drop if the inclusions threaten the stone’s durability. Star sapphires, like the one pictured, are quite rare. The best and most expensive star sapphires are semi-transparent, with just enough silk to create a well-defined star. 

Cut is another important factor in the appearance of any gemstone. To achieve the best overall color, maintain the best proportions, and retain the most weight possible, gemstone cutters focus on factors like color zoning, pleochroism, and the lightness or darkness of a stone.

Carat weight allows for precise measurements. Blue sapphires can range in size anywhere from a few to hundreds of carats, and large blue sapphires are more readily attainable than large rubies. However, most commercial-quality blue sapphires weigh less than 5.00 carats.
