The ‘gem of the heavens’, the name is derived from the Greek sappheiros meaning blue.
It is the birthstone for September and the anniversary gemstone for the 5th and 45th years of marriage. Sapphires are available in a wide range of colour except red. Sapphire in colours other than blue are called fancy sapphires. Colours variations include white, pink, yellow, peach, orange, brown, violet, and green. The most valuable sapphires have a medium intense, vivid blue, few visible inclusions and hold their brightness of colour under all different types of lighting. Any black, green, or grey overtones will reduce a stone’s value.
The most valuable are genuine Kashmir stones, Burmese sapphires are valued almost as highly and then we have Ceylon (Sri-Lankan) sapphires. Click here to read full article. Sapphire – September birthstone
