Hint :Sapphire is a delicate gemstone made up of aluminium oxide (α-Al₂O₃) and trace quantities of other elements including copper, titanium, chromium, vanadium, and magnesium. Normal "fancy" sapphires come in a variety of shades, including black, purple, orange, and green; "parti sapphires" have two or three colours. Red corundum stones are also used, although they are referred to as rubies rather than sapphires. Depending on the location, corundum may be graded as ruby or sapphire.

Sapphire is an impure type of alumina that incorporates impurities such as cobalt (Co).
Natural sapphires are commonly sliced and polished into gemstones, which are then worn in jewellery. Big crystal boules may also be produced synthetically in labs for manufacturing or cosmetic purposes. Sapphires are used in certain non-ornamental applications, such as infrared optical components, high-durability windows, wristwatch crystals and movement bearings, and very thin electronic wafers, which are used as the insulating substrates of special-purity semiconductors, due to their remarkable hardness – 9 on the Mohs scale (the third hardest mineral, after diamond at 10 and moissanite at 9.5).
Note :
Aluminium oxide, also known as Al₂O₃, is a chemical compound made up of aluminium and oxygen with the formula Al₂O₃. It's the most common of many aluminium oxides, and it's officially known as aluminum(III) oxide.
