It is a very desirable gemstone due to its excellent color, hardness, durability, and luster. In the gem trade, Sapphire without any color prefix refers to the blue variety of the mineral Corundum. However, the term Sapphire encompasses all other gem varieties and colors of Corundum as well, excluding Ruby, the red variety of Corundum, which has its own name since antiquity. Sapphire is used in all forms of jewelry, including bracelets, necklaces, rings, and earrings. It is used both as centerpiece gemstone in pendants and rings, as well as a secondary stone to complement other gemstones such as Diamonds. Blue sapphire symbolizes honesty, clarity of feelings, and deep emotional attachment. he same holds true for all other color varieties of Sapphire. However, the word "Sapphire" in its plain context refers only to blue Sapphire, unless a prefix color is specified. Sapphire with a color other than blue is often called a "fancy" in the gem trade Review: Not the best - Not the best quality but good enough for display. Review: Sapphire is my birthstone. But this raw crystal speaks to me. I have much to learn with it; I’m looking forward to making a pendant with it. ## Features - The color of a blue sapphire is more important than its clarity. Sapphires are rarely completely clean and even very expensive stones can be slightly included. Subtle differences in color can make great variations in valuations of fine gemstones. Fine loose gemstones of good color and clarity are always rare and valuable. Highly saturated medium or medium dark blue tones are best, blue sapphires which are too dark or too light are worth considerably less. - Color zoning is responsible for certain Sapphires having lighter and darker colors in different parts of a crystal. Some Sapphire gemstones may even be multicolored such as purple and blue. Sapphire is a tough and durable gem, and the only natural gemstone harder than Sapphire is Diamond. Despite this, Sapphire is still subject to chipping and fracture if handled roughly, and care should be taken to ensure it is properly handled. - Display a lighter and more intense color when viewed at different angles. Some pleochroic Sapphire is blue when viewed at one angle, and purple at a different angle. Color zoning, which forms from growth layers that build up during the formation of the stone, may also be present in certain Sapphires. - Our Expert gemologists verified this Blue Sapphire which passed many quality base tests and get stone certified through which we are completely assured of Top Quality Gemstone.
