The word “ruby” comes from ruber in Latin which means red. Prior to 1800, red gemstone including red spinel and red garnet were both considered as ruby. Like sapphire, ruby is a variety of mineral called corundum, its main components consist of aluminium and oxygen (aluminium oxide). The ruby is formed when chromium is mixed into the pure corundum which is colorless. For ruby, 1% of chromium is the best amount, but as the chromium amount becomes excessive, the color will turn to grey and result in just an ordinary mineral that doesn’t have any beautifulness. In term of its hardness, ruby has a hardness of 9.0 in Mohs scale, second to diamond which is 10.
Among the corundum, only those that are red will be considered as ruby, the rest will be considered as sapphire. The mining operation in Mogok valley, Myanmar started in 15th century, and later became the main source of rubies. The most significant characteristic of Mogok rubies is its gentle color. Its color is said to be on par with the sapphire from Kashmir and emerald from Colombia (Muzo Mine). In comparison, Mogok rubies are better than Thai rubies, Kashmir sapphires are better than Mogok sapphires, and Muzo emeralds are better than Zambia emeralds. When compared to each other, the better version of the gemstones all have an indescribable yet attractive gentle color.
The main source of rubies is Mogok in Myanmar, while Thailand and Sri Lanka were not regarded as significant as Mogok due to the low quality and quantity of rubies. However, the rubies production from Mogok dropped drastically after the Burmese coup in 1962 and the nationalization of the mines. At that time, the Thai rubies from Thai-Cambodia border including Pailin in Cambodia, that was considered as low quality, were reconsidered again as the technology of color enhancement by heating improved. This lasted until 1993, when the rubies from Mon Hsu in Myanmar gained its share in the market and replaced Thai rubies. Other than the places mentioned, East Africa and Vietnam are also known to produce rubies.
