For individuals seeking engagement ring choices, a ruby is a gorgeous and long-lasting gemstone. A ruby is gubelin certified gemstone that ranges in colour from pink to blood red and is a variation of the mineral corundum (aluminium oxide). Sapphires are other gem-quality forms of corundum. Ruby, along with amethyst, sapphire, emerald, and diamond, is one of the classic cardinal stones

The name ruby derives from the Latin word ruber, which means "red." The element chromium is responsible for a ruby's hue. Some rubies, such as the Black Prince's Ruby in the British Imperial State Crown, are really spinels, despite their popular or historical names. These were previously referred to as "Balas rubies."

A ruby's quality is defined by its colour, cut, and clarity, which, combined with carat weight, influence its value. The brightest and most costly hue of red, known as blood-red or pigeon blood, fetches a significant premium above other rubies of comparable grade. Clarity comes after colour: like diamonds, a clear stone will fetch a premium, but a ruby with no needle-like rutile inclusions may imply that the stone has been treated.
