Red corundum weighing 11.6 kg has reportedly been detained at Manas Airport in Bishkek.

There are two red corundum deposits in Kyrgyzstan and both of them are located in the Batken region.   

The Rajaratna Ruby is one of the world’s largest rubies. It is a 2,475 carat, cabochon-cut wonder, currently located in Bangalore, India and owned by Mr. G. Vidyaraj.

This truly regal ruby, whose name literally means “King of Rubies” in Sanskrit, was deemed the world’s largest ruby and the world’s largest star ruby at the time of its unveiling in 1986, and still considered one of the world’s largest rubies today.  Furthermore, this ruby is believed to have a six-ray star pattern (known as asterism) unlike any the world has ever seen due to its semi-translucent, opaque nature rutile fibers and cabochon cut.

A ruby is a pink to blood-red colored gemstone, a variety of the mineral corundum.  Other varieties of gem-quality corundum are called sapphires.  Ruby is one of the traditional cardinal gems, together with amethyst, sapphire, emerald, and diamond.  

The quality of a ruby is determined by its color, cut, and clarity, which, along with carat weight, affect its value. The brightest and most valuable shade of red called blood-red or pigeon blood, commands a large premium over other rubies of similar quality.  

Rubies, as with other gemstones, are graded using criteria known as the four Cs, namely color, cut, clarity and carat weight.  Rubies are also evaluated on the basis of their geographic origin.
