Myanmar has been a significant source of Spinel for centuries. The Mogok region in Myanmar is renowned for producing high-quality spinel, including the famous "Mogok Ruby," which is actually a red spinel. Other regions in Myanmar, such as Mogok and Namya, also yield spinel deposits. Sri Lanka, historically known as Ceylon, is famous for its gemstones, including spinel. The Ratnapura district in Sri Lanka is a notable spinel mining area. Sri Lankan spinel is known for its range of colors, including vibrant red, pink, and blue.

Thailand is a hub for the Gemstone trade, and spinel is among the Gemstones mined and traded there. The Bo Rai and Chanthaburi regions in Thailand are known for spinel mining. The availability and quality of spinel can change over time as new deposits are discovered or existing ones are depleted. Additionally, the specific locations and mining operations within these countries can vary, so it's always advisable to consult current sources and experts for the most up-to-date information on spinel mining and reserves.

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.‎

The availability and quality of spinel can change over time as new deposits are discovered or existing ones are depleted. Additionally, the specific locations and mining operations within these countries can vary, so it's always advisable to consult current sources and experts for the most up-to-date information on spinel mining and reserves. 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.‎

Tanzania is a significant source of spinel, particularly in the Tunduru region. Spinel deposits in Tanzania can yield a variety of colors, including red, pink, blue, and violet. Mahenge spinel, known for its pinkish-red hues, is highly sought after. Vietnam is known for its spinel mines, with primary deposits located in the Luc Yen and Quy Chau districts. Vietnamese spinel is known for its vivid red and pink colors. Afghanistan is another country where spinel can be found. The Jegdalek and Pamir regions are known for spinel mining. Afghan spinel is known for its vibrant red and pink colors.
