Gemstones are found in countries all around the globe, although some parts of the world are much more abundant in these precious stones than others. So which countries have become the biggest sources of gemstones and diamonds? To answer this, the team at BriteCo created a world map that highlights the top-producing country for more than 30 different gemstones.
The map was created using data from the United States Geological Survey (USGS)’s Mineral Yearbook 2020, which tracks the amounts of different types of gemstones, diamonds, and other minerals that countries around the world produce each year. The team looked at countries’ production of each type of gemstone in kilograms from 2016 to 2020 to determine each material’s top producer.
Several gemstones also include a secondary country on the map to acknowledge nations that may not be the top-producing country but still contribute a significant amount of the gemstone to the global supply. Explore the world map and gemstones chart below to see which countries are the biggest producers of 35 of the most dazzling and sought-after gemstones on the market.
Which Country Produces the Most Diamonds?
The country that produces the most diamonds is Russia, with 113,600 thousand carats produced between 2016 and 2020. This large amount translates to 22,720 kilograms worth of diamonds, for a more direct comparison to the other many other gemstones on the list.
Russia produces 31% of the global supply of diamonds, most of which is supplied by diamond mining company Alrosa. Canada produces the second-most diamond gemstones in the global supply, with 91,260 thousand carats mined during this time. Other large diamond producers around the world include Botswana, Angola, and South Africa.

Which Country Produces the Most Emeralds?
According to the USGS data, Zambia produces the most emeralds in the world. Between 2016 and 2020, the country produced 129,400 kilograms of emerald gemstones. Emeralds from Zambia have grown in popularity due to their level of clarity, the depth of their color, and their tendency to be stronger than other countries’ emeralds.
Zambia is also known to produce the largest emeralds, with some weighing in at more than a kilogram each! Just one mine in Zambia, the Kagem Mine, is the single largest producer of emeralds in the world, accounting for 25% of the entire global supply of emeralds.
Which Country Is the Top Producer of the Most Gemstones?
Tanzania is the top-producing country for the most gemstones, with the highest production rate for six on our list of gemstones. The six gemstones Tanzania was found to produce the most of are aquamarine, garnet, ruby, sunstone, tanzanite, and tourmaline. Tanzania’s most plentiful gemstone is garnet, with the country producing 765,768 kilograms of the dazzling red gemstone between 2016 and 2020.
What Is Tanzanite?
This blue and purple gemstone was discovered in Tanzania, which led the jewelry company Tiffany & Co. to give it the name Tanzanite in the 1960s to capitalize on the gemstone’s rarity and the fact that it can only be found in one location in the world. The gemstone’s scientific name is blue zoisite, and it is one of the official birthstones of December.
