RUBY: THE KING OF GEMS
- Written by E. M. Gems & Diamonds
Rubies have always been fascinating from the ancient times till now a days. In this article will try to introduce you to the world of rubies so that you know a little bit more in your next ruby shopping.
Of the natural gem materials, ruby is second only to diamond in hardness and is considered one of the four precious stones, together with sapphire, emerald and diamond.
Ruby is the red variety of corundum and it occurs as bright red, red, purplish or brownish-red and deep pinkish-red colors. The red color is caused mainly by the presence of the element chromium.
The word "ruby" comes from the Latin word ruber, which means red.
Elements determing the value of ruby
Prices of rubies are primarily determined by color. The brightest and most valuable "red" called blood-red or "pigeon blood", commands a large premium over other rubies of similar quality. The most preferred color is a deep blood red with a slightly bluish hue. Such Ruby is known as "Burmese Ruby" or "Pigeon's Blood Ruby".
After color follows clarity: similar to diamonds, a clear stone will command a premium, but a ruby without any needle-like rutile inclusions may indicate that the stone has been treated.
Cut and carat (weight) are also an important factor in determining the price.
Rubies have historically been mined in Thailand, the Pailin and Samlout District of Cambodia, Burma, India, Afghanistan, Australia, Namibia, Colombia, Japan,Scotland, Brazil and in Pakistan.
The world's most expensive ruby is the Sunrise Ruby.
The Sunrise Ruby is the world's most expensive ruby, most expensive coloured gemstone, and most expensive gemstone other than a diamond. In May 2015, it sold at auction in Switzerland to an anonymous buyer for US$30 million.
