Sapphire, which has a nice English name - sapphire, is derived from the Hebrew word "sappir", meaning "to perfection." Sapphire is the world's five largest treasures of stone, known as the "stone of destiny." The main component is aluminum oxide Al2O3. Due to its hardness of 9 and a high refractive index, it is the most important gemstone type except diamond.
There are not many world sapphire producing areas, mainly Myanmar, Sri Lanka, Thailand, Australia, China, etc., but in terms of gem quality, Myanmar and Sri Lanka have the best quality. Depending on the geological origin, it can be divided into two categories: one is sapphire produced in Myanmar, Sri Lanka and Kashmir, India. The other category is sapphire from Australia, Thailand and China.
The sapphire of Myanmar and other real estates, due to the coloration of titanium, is bright blue, containing silky rutile and fingerprint-like liquid inclusions. The silky rutile inclusions can produce six or twelve starlights and are of high quality gemstones.

The most characteristic is that there is a crack in the shape of a lotus leaf around the black solid inclusion body. The three groups of polycrystalline twin crystals developed, and the cracks split along the double crystal plane.
