Practically all blue sapphires in gem quality from Burma (now Myanmar) have appeared in alluvial deposits along the Mogok Stone Tract. The Ruby Land: Gemstones and Geology of Myanmar's Mogok Stone Tract

Mogok is a historical town in the north of Myanmar (Burma), located in a basin 50 leagues westward of the meandering Irrawaddy River, about 3,500 f. above sealevel. Myanmar is littered with Buddhist treasures and gold-clad couples, such as those in Kyauk Pyat That Abbey, which rise from the crags. The Mogok is known for its precious stones like ruby, saphire, spinell, pearidot and moons.

The Mogok Stone Tract hill was a legend for hundreds of years for such an astonishing wealth that natives came across gems glistening in the bush. This area is still world-famous for its gems: There is a roadshield along the motorway that says "Welcome to Rubinland", where there are now about 1,000 working landmines and excavations; most of the world's best gemstone ruins come from Myanmar, most of them from Mogok.

This group of females use a basket of treasures to collect gems, such as goldminers looking for precious stones, from the rinsing out of a precious stone workstation. He is one of the few fortunate people who have travelled to Myanmar in recent years. Up until 2011, the land was governed by a army june, and even for scientists travelling was severely limited.

A group of museum gemologists was given the long-awaited chance to visit Mogok in November 2013 to investigate the fascinating geologic development of Ruby Land. "Why was the rainforest so full of precious stone grade mineral, which is by nature scarce? He was accompanied by curator James Webster, who is studying magma lawsuits, and senior scientific assistant Jamie Newman on a Constantine S. Niarcho mission sponsored by the Stavros Niarchos Foundation.

On the journey, mineralist George Harlow and geographer James Webster (right) gathered more than 200 lbs of copies and made a note at each stop. In contrast to other natural assets, gems are not usually formed in large occurrences of ores. Instead, the reservoirs are usually small and can only be found in certain geological surroundings.

Mogok Stone Tract is one of a kind because it contains several very different surroundings that give an indication of why the area is so full of gems. Among these springs are magmatic intrusives, so-called pegmatite, which can create large jewel bags in other stones. They responded with existing stone (called by the explorers country rock) to make sapphires, moonstones and certain precious stones.

Metamorphosed by the use of temperature, compression and liquid flowing past, it turned lime stone into stone and produced mogok ruby and spinel, a related diamond, during mining 200 million years ago. As a result of the decomposition of all these stones, rivers and caves have formed which, from a historical point of view, are the wealthiest of all. A further reason for the existence of certain gems in Mogok, says Dr. Webster, could be the age old flow of extreme high temperature aqueous liquids through the earth's surface, which could have contributed to the dissolution and formation of salts in arteries or in contact between different kinds of stones.

"It' really about getting warm," says Webster. "It must have eventually disintegrated certain things from the rock-changing mineri in other mineri. "It is hypothesized that part of the Mogok deposit of the stone aluminium oxide - a very tough stone, the second most important after the stone and known to us in its reddish shape as ruby and in many other colours as saphire about 15 to 25 million years ago.
