Sapphire means blue. But sapphire comes in more than one colour. The blue-coloured sapphires have been named blue sapphires, and other colours are known as fancy-coloured sapphires. Sapphire gets formulated by corundum.

The aluminium oxide found in corundum is pure and contains iron, titanium, and chromium. These minerals are responsible for the sapphire’s blue, yellow, pink, purple or green colour.

Sapphires are also available in grey, black and brown, and the grey ones can turn white or even colourless when heated.

Corundum that forms pinkish-orange gems are called padparadscha, and this is the most expensive sapphire. It costs more than the best quality blue sapphire.

Artificially sapphires can be made too, and these synthetic stones cost much less than the originals.

Sapphires are found in many places, including India, Sri Lanka, Madagascar, Thailand, Myanmar, Australia, Kenya, Afghanistan, and Montana of the U.S.A.

Not only in jewellery but also in laser, it gets used. The wafers of sapphires are utilised in the making of watch faces. They are also helpful in making Xenon Arc Lamps and windows of high-pressure chambers for spectroscopy.


What is Ruby?

Ruby is categorised as a precious stone. It is formed by a mineral named corundum. This stone is red and gains its colour from the chromium in the problem.

Sometimes rubies become dark, having a purple tone. These are not as valuable as blood-red coloured rubies.

Heat gets used on the ruby to improve its colour. This heating is capable of changing rubies eternally. Ruby is a durable stone that gets used mainly in jewellery making. However, the first laser was formulated with the use of artificial ruby.

The price of the gemstones gets fixed based on their rarity, size, colour, cut and, most importantly, clarity. Rubies in large sizes are very hard to find and can even cost more than diamonds. Rubies over two carats are too rare to get hold of.
