Sapphire (from the Hebrew spir - "Sapir" - from the texts of the Bible, although the Bible rather referred to another stone - lapis lazuli) is a type of mineral - corundum. Any jeweler-quality corundum crystal that is not red in color (red corundums are called rubies) is called a sapphire. Most often, sapphire is blue. The corundum that forms sapphire is colorless in its pure form. The special color is given by various additives, for example iron, chrome.

Different shades of blue are given to sapphire by iron and titanium admixtures. If the crystal has an insufficient amount of such an impurity, it has a light, gray color and a lower value.

Yellow and green color is also given by iron admixture. Pink sapphires have an admixture of chromium. If there is more chromium, the stone is closer to red and is considered a ruby.

Violet, purple colored corundum has an admixture of vanadium. Such gems are traditionally less valuable.

White sapphires (leukosapphires) are most often initially slightly brownish or yellowish. The pure color is obtained by heating them. Pure colorless corundum is very rare.

There are also sapphires that change color in different lighting – blue in daylight and purple in artificial lighting.
