Buying Sapphire and Determining Sapphire Value Sapphire Color Blue is indeed the best-known and the most valuable of sapphire colors. The prized Kashmir and Burmese sapphires have a deep blue that is described as both intense and velvety. These sapphires are not often seen on the market today. Sri Lankan and Madagascar sapphires are the most common today, with a wide range of colors from light blue to dark blue. With blue sapphire, the intensity of blue is the most important factor. For example, a huge sapphire with a washed-out, weak blue color is much less valuable than a much smaller stone of excellent color. An intense, rich pure cornflower blue that is not too dark or too 'inky' is the most desirable color. Overall, sapphires that are too dark or too light in color are less valuable, but light-blue sapphires often have greater brilliance that is rarely found in darker blue stones. Colorless sapphires are actually quite rare, since most stones will exhibit some faint hints of color. In the gem trade, when referring to sapphire, blue sapphire is the official designation; all other colors, including pink, green, orange, purple and white sapphire, are referred to as 'fancy sapphire'. Sapphire Clarity and Luster Sapphire can occur transparent to opaque. Transparent materials are the most valuable. Some translucent materials are cut into beads or cabochons. Opaque materials have very little gemstone value, although they may sometimes be used for ornamental carvings. Sapphires are generally cleaner than ruby, so it is best to look for stones that are eye-clean. Eye-clean stones in larger sizes are quite rare, especially in ideal colors. Sapphire Cut and Shape Various shapes and cutting styles are common with sapphires. Ovals, cushions, and rounds are commonly seen, as are other shapes, such as fancy hearts, pears and emerald cuts. Round stones can command very high premiums, especially in diamond-cut calibrated stones weighing 1 carat or more. Sapphire Treatment The most common treatment for sapphire is heat treatment, though unheated sapphire specimens can be found. Stones are heated (generally before they are cut) to between 1700 to 1800 degrees Celsius (3100-3300 degrees F) for several hours. Most sapphires today are heated, and unheated stones in rich blue can command enormous prices in today's market. All sapphire treatments should be fully disclosed by any reputable dealer.
