In 2002 rubies were found in the Waseges River area of Kenya.

Ruby is considered one of the four precious stones, together with sapphire, emerald and diamond.

For example, the first working laser was a ruby laser, made from ruby (chromium doped corundum).

The technical problems seemed insurmountable, so researchers since the 1960s have sought to deposit GaN on a base of readily available sapphire.

For example, high temperature crucibles made of iridium are used in the Czochralski process to produce oxide single crystals (such as sapphires) for use in computer memory devices and in solid state lasers.

Today, blue lasers use a sapphire surface covered with a layer of gallium nitride (this technology is used by Japanese company Nichia, which has an agreement with Sony), and blue semiconductor lasers use a gallium nitride mono crystal surface (Polish company TopGaN).

The color of fine blue sapphires may be described as a vivid medium dark violet to purplish blue where the primary blue hue is at least 85 and the secondary hue no more than 15 , without the least admixture of a green secondary hue or a gray mask.
