Unique combination of colors from the ... Extinct rubies
In the Burmese rubies there is an almost mystical appeal to them. For many, they are considered to belong among the best precious stones in the world.
Their particular color is the result of two factors, according to the book “Ruby & Sapphire: The Guide to a Gemmologist”.
The first factor is a combination of the slightly blue-red color of the gemstone base along with the “cleaner” red fluorescent emission, working together to give this high intensity to the color.
The second factor is the presence of “silk”, that is, the tiny clusters that disperse the light upward, giving color a softness and greater dispersion across the surface of the gemstone.
While other rubies from different sources have the strong red color they do not compare to those from Burma. Perhaps this is the special combination of the factors we mentioned that classify the particular rubies at the top of the list.
Burmese rubies are much newer than those from East Africa. Of course, this is true of all the rubies created by the conflict between the Indian continent and the Asian continent.
During some tectonic conflicts in history, they have led to major changes in the surface of the Earth, resulting in the formation of minerals and the creation of regions called orogenic zones. Many of the mines with the finest rubies and sapphires fall into these zones, according to the Hughes book.
The Panagorean orogeny occurred about 750-450,000,000 years ago, where beautiful landscapes were created in Kenya, Tanzania, Mozambique, Madagascar, Sri Lanka and southern India.
Meanwhile, the activity of 45 to 5,000,000 years ago has resulted in the Himalayan region, the creation of ruby and sapphires from Afghanistan and Tajikistan via Pakistan, North India, Nepal and Myanmar, and then China and Vietnam
There is no easy way to determine the exact age of rubies, but there is a distinction between the rubble from the Himalayas with those originating in East Africa and Sri Lanka
Unfortunately, there is not a large amount of excellent ruminants from Burma, most mining operations being made in Mogok, according to Hughes.
Burmese rubies can only be compared with the rubies from Mozambique because of the difference in iron content in the soil, resulting in a similar shade of red, according to Secrets of the Gem Trade.
This is good for the ruby industry, because they can place on the market precious stones approaching the quality of rubies from Burma. In fact, it is estimated that about 85 per cent of the ruby market today is made up of Mozambique.
And as production from Burma will continue to decline, supposing that Mozambique’s supply of Romanians will remain strong, it is likely that the proportion that exists today will diminish.
