Saturation in the commercial grade is usually from 1 to 3. In commercial grade Blue Sapphire you can expect to see the hue range from violet (V) to a very strongly greenish blue (vstgB), and tones will range between 2 and through 8, but less of a saturation range. We prefer to use the GIA Colored Stone Grading System, this is an exceptionally good method for noting the quality of color stones. The Blue Sapphire color next on the popularity scale is Cornflower Blue. The Cornflower Blue or Medium Blue color shades vary but all usually allow more light into the stone for a brighter appearance, so these stones are usually cut in the Cushion or Oval shape to make it as brilliant as possible. Price per carat reflects the size, evenness of the color, the clarity and the brightness of the stone. There are an array of color grades, and prices, and sometimes it's difficult to know what quality of color to expect in stones at various prices. Although everyone has heard of the fabled Burmese Kashmir Sapphire, few have ever seen one. We constantly see appraisals that refer to Kashmir Sapphire (or Cashmere Sapphire), but it is usually referring to a Top Gem Ceylon Sapphire from Sri Lanka. The term Kashmir is widely regarded to mean the finest quality Blue Sapphire with a velvety, slightly violetish blue, highly saturated in medium to medium dark tone, with sleepy transparency. Once in a great while we are able to acquire one from Burma, but since the mine has been depleted and these highly prized stones are old stones that are simply brought back onto the market, they don't last long. Authentic Kashmir Sapphires and the Kashmir color Sapphires carry a particularly high cost per carat and are very highly valued Collectors Gemstones. Sapphire is in the Corundum (ko-RUN-dum) mineral family. Its hardness of 9 places it next to Diamond (10), making it an excellent choice for jewelry worn daily. Blue Sapphire is frequently featured on engagement rings. Most people relate Sapphire to the color Blue. Sapphire's popularity is not based on color alone. Sapphire and Ruby comprise more than half of all Gemstones sold worldwide.
