Gemstone Localities Around the World

Gemstone localities are found all over the world, so there are no particular locations where only gems are found. However, some states like Brazil, Burma, India, Mozambique, Tanzania and more have higher quality and more varied gems deposits.

We source many gemstones for our quality jewelry pieces and they come from all over the world. Gemstones are defined by the World Jewellery Confederation as “natural inorganic material” and, with the exception of pearls, which are organic, they come from very specific locations.


South America’s Gemstone Localities

South America has an extensive history of gemstone production and arguably produces some of the finest gem specimens in the world. Out of the South American gem-producing areas, Brazil is by far the most prolific source of world-class gemstones. There is an enormous variety of gem types found in the country including aquamarine, amethyst, citrine, diamond, emerald, quartz, ruby, sapphire, topaz, tourmaline and many more.

While Brazil is well known for its incredible range of gorgeous gems, Columbia represents the source of perhaps the finest emeralds in the world. Other countries in South America also help to expand the range of gems available from this one continent with Bolivia, Chile, Guyana, Peru, Uruguay, and Venezuela. They all provide a source of quality gemstones. Chile is a leading producer of beautiful blue lapis lazuli.

Europe’s Gemstone Localities


Without Russia, Europe is one of the less prolific producers of gemstones.

Russia is the world-renowned source for exquisite Diamonds and Garnets. Russia also provides the widest variety of gemstones of any country on the European continent; including alexandrite, diamonds, lapis lazuli, topaz, tourmaline, garnets, and emeralds.

Poland continues to be the premier source for high-quality amber across the globe.

Other gemstone deposits in Europe can be found in Spain, which produces aventurine, agate, and quartz. Spectrolite, a form of labradorite, can be found in Finland, and thulite is deposited in Norway. The United Kingdom is a source of fluorite and the only known source of Blue John in the world. Czech Republic is renowned for producing the best Moldavite in the world. Moldavite is a naturally forming glass that is believed to have formed because of a meteorite impact in southern Germany.

Nepal claims some of the best Garnets ever found. On the whole, Asian countries are prolific gem producers with Jade, Garnet, Sapphire, Diamond, Spinel, Aquamarine and Amethyst all mined across Asia.

From Indian  Diamonds to Vietnamese Sapphires, many countries throughout Asia contribute to the continent’s gem production. The growing gemstone industry in Afghanistan is opening up an extensive range of gems to a broader market. This once amateur industry is being formalized allowing more quality stones to be mined and exported. Four prominent regions in Afghanistan hold deposits of the emerald, ruby, lapis lazuli, aquamarine, and sapphire. There are very few known deposits of Lapis in the old world, and even though the ancient chronicles tell tales of Lapis mines in western Egypt and southwest Iran, the only currently confirmed deposits lie next to the Baikal lake, in the Pamirs and most of all, in Afghanistan.

Africa’s Gemstone Localities

Gemstone Localities in Africa

Africa, home of many gemstones


While most people will know that Africa is the major source of diamonds, the colored gemstone trade is gradually becoming more significant.

Kenya, Tanzania, and Mozambique sit on a wealth of gemstones including rubies, sapphires, tanzanite, alexandrite, aquamarine, rhodolite, Tsavorite garnet, and tourmaline. Frequently gemstones reflect their source, for example, Tanzanite comes from Tanzania and Tsavorite comes from Kenya’s Tsavo National Park.

Madagascar is the large island off the southeast coast of Africa. It is a leading supplier of sapphires along with aquamarine, quartz, morganite, tourmaline, tsavorite, demantoid garnet, and labradorite.

Mozambique has also become one of the famous producers of Paraiba Tourmaline, and most of the global supply of Paraiba now originates from Mozambique. Perhaps the most important mining operation in Mozambique at the moment are the Mozambique Ruby mines.

Nigeria is highly-regarded for the blue sapphire as well as large quantities of fine tourmaline. Nigeria is also well-known for Almandine, Garnet, Aquamarine, and Topaz.

Meanwhile, Tanzania is a massive source of gems. It is particularly well-known for Tanzanite. Tanzanian Spinels from Mahenge have been in the spotlight. The colors of these Spinels can rival the most beautiful Rubies and have been steadily increasing in popularity. Other gemstones from Tanzania include the stunning Rhodolite Garnet, Tsavorite Garnet, and several exclusive stones such as unheated zircon. Mozambique also boasts excellent tourmaline in various colors.

As you would probably imagine, much of the gems are sourced in the western regions of the USA. Colorado, Arizona, and Nevada, but lesser known are the areas of North Carolina, Tennessee, Arkansas and even Maine.

The regular names that we associate with Gemstones, such as Emeralds, Rubies, Beryl, and Sapphires are all mined in the USA. But there are also many unique stones that are peculiar to the region!

Unique to USA Gemstones is the Oregon sunstone. Sunstone has lovely copper, red and burnt umber tones and a glowing disposition that makes it a significant choice for jewelry.

The USA is the world’s largest consumer of gemstones. More gemstones are actually sold in the USA than in any other country in the world. Over 99% of these gems are imported as there is very little domestic production. Most of the gemstones are mined in developing countries.


As the story about gemstone localities shows, gems come from every part of the world. They are mined, cut and polished to meet the market demand.
