The most important places with reserves of this mineral in Myanmar, Tajikistan, Sri Lanka, South of Asia, Thailand

Myanmar, Tajikistan, Sri Lanka, South of Asia, Thailand, Vietnam, Cambodia have the best Spinel quality called "ruby". Other countries such as Afghanistan, Nepal, Australia, Tanzania, Madagascar, Nigeria, and southwestern Kenya also have good veins. In Vietnam, near the Luc Yen region, the extraction of spinels and rubies has begun in earnest since 1990, when most spinels are pink.
In Tanzania, in the 1980s, red-pink to cherry-red spinel Stones and a neon effect were found in mines around Morogoro County. Today, there are reports of clear, cut spinels ranging in size from 10 to 50 carats. Tanzania has been reported. But let's look at the most important places with reserves of this mineral:
Badakhshan Spinel (La’al) mine in Tajikistan and its history
The ancient and historical mine of Badakhshan (La’al Mountain) near the Murghab region in the east of Badakhshan province, whose spinels are known in ancient Iran as "La’al Badakhshan", is one of the most important deposits of La’al Stone in modern Tajikistan. The mine is said to have been discovered due to a strong earthquake and the subsequent collapse of large Rocks from the mountain and the damage caused by it.
At an altitude of 2,900 meters between Kurog and Vashkashim along the Panj River, on the border between Tajikistan and Afghanistan, is the La’al Mountain mine, which has about half of its spinels red and the rest pink. Mining of this mine started in the 7th century AD and it is said that famous stones such as Timur Ruby and Black Prince ruby, which were originally spinel, were extracted from this place.
During the twentieth century, due to the geographical and closed conditions in the Soviet Union, these mines were less known. In the war between the Russian and British empires over colonialism and the demarcation of borders in western Asia, because Russia had little interest in jewelry, these mines were mapped on the Afghan-Russian border and somehow hidden from the world.
