This sought after red gemstone has been extracted since the 8th century BC in Sri Lanka and has been adorning the royal families jewels in India and around the world, up to the present day. The name corundum derives from 'kuruntam' in Tamil, the language spoken in south east India. Ruby is probably also the most valuable colourful gemstone, whether is it as cut stone or mineral specimen. Here is a superb and pristine specimen of rich colour ruby (1.8 cm crystal) with sharp faces, ideally set on a contrasting marble matrix. From the world famous Mogok mine, how of the best collectible rubies knows.
