Jewellery | ˈdʒuːəlri | (US jewelry) noun [mass noun]
Personal ornaments, such as necklaces, rings, or bracelets, that are typically made from or contain jewels and precious metal: She had silver hair and chunky gold jewellery | [as modifier]: A jewellery box.

Sapphire is a gemstone variety of the mineral corundum, an aluminium oxide (α-Al2O3). Whilst typically associated with the colour blue, sapphires can also naturally occur in a wide variety of colours such as blue, yellow, purple, orange, green colours - which are also called "fancy sapphires". "Parti sapphires" are those sapphires which show two or more colours in a single stone. The only colour which sapphire cannot be is red - as red coloured corundum is called ruby, another corundum variety. Commonly, natural sapphires are cut and polished into gemstones and worn in jewellery.

They also may be created synthetically in laboratories for industrial or decorative purposes in large crystal boules. Because of the remarkable hardness of sapphires – 9 on the Mohs scale (the third hardest mineral, after diamond at 10 and moissanite at 9.5) – sapphires are also used in some non-ornamental applications, including infrared optical components, such as in scientific instruments; high-durability windows; wristwatch crystals and movement bearings; and very thin electronic wafers, which are used as the insulating substrates of very special-purpose solid-state electronics (especially integrated circuits and GaN-based LEDs).
