Whenever we hear the word diamond, the idea that comes to mind is the sparkling jewels, the sign of everlasting love, the glitz of the red carpet. And beyond this glitter is a world of great geological pressure, deep-earth formation, and gigantic economic power. Diamonds are beautiful and it is one of the most valuable and strategically important natural resources on the planet.
And yet where are these precious things found? What countries are the key holders to the diamond treasury of the world? The solution is an exciting trip all around the globe, into the distant Arctic circles, the expanses of African deserts and the icy depths of Siberia. Learning about diamond reserves is not merely a matter of carat count, but rather a question of geopolitics, economic security, growth of technology used in mining the jewel, and the future of one of the most legendary commodities in the world.
We are going to dig deep into the top 10 countries with highest diamond reserves in this definitive guide. We will go beyond the mere lists to the individual accounts, key mines and economic importance of the hidden treasure of each country. This article will give you a clear, authoritative and comprehensive overview, whether you are a geology enthusiast, or just interested to find out the origin of these extraordinary stones.
An important distinction which is important to understand Diamond Reserves
It is important to know what we are talking about when we talk about reserves before we get into the list. Terminology is not something that can be taken lightly in the mining world where not all diamonds are created equal.
Diamond Resources: This is the total value of the estimated amount of material that contains diamonds that is in the ground. It is a wide, frequently wishful, figure, which contains deposits which cannot be mined economically or technologically today.
Diamond Reserves: It is that part of the resources that are found to be economic to extract with current technology. Reserves are the bankable ones — the ones that mining companies can be certain to mine and sell at a profit.
This article dwells on proven and probable diamond reserves, this is because it is the true measure of immediate and tangible diamond wealth a country has. The facts are summarized using authoritative sources such as the United States Geological Survey (USGS), company reports of key players, such as the industry giants De Beers and ALROSA, and market research of leading companies.
