Which Countries Mine the Most Gemstones of Each Type?

Diamonds and other precious gemstones are naturally occurring all around the world, although some countries are far more abundant than others when it comes to these stunning jewels. Just check out this chart created by Brite.co that maps out the countries where the most of each type of gemstone is produced using data from the U.S. Geological Survey’s Mineral Yearbook 2020. The map highlights the top-producing country for each of the thirty-five gemstones analyzed. For several gemstones, it also highlights the second top producing country as long as that country has also contributed a significant amount of the gemstone to the global supply.


So where are dazzling diamonds most commonly produced in the world? Russia has been the world’s biggest producer of diamonds since 2016 and produced 22,720 kilograms of diamonds between 2016 and 2020. Canada isn’t far behind as the chart highlights them as the secondary-producing country with 18,241 kg of diamonds produced during that time. As you peruse the chart of gemstones you may notice Tanzania’s name continually pop up as the top producer for several gemstones. This East African nation is rich in precious stones and was found to be the top-producing country for six of the thirty-five different gemstones: Aquamarine, Garnet, Ruby, Sunstone, Tanzanite, and Tourmaline. Tanzanite is a rare blue and purple gemstone that can only be found in one location in Tanzania, hence Tiffany & Co. dubbing the gorgeous stone as “Tanzanite”.
