Diamonds are found on every continent except Europe and Antarctica. The regions are polar -- Canada; desert -- Australia; tropical -- India, Brazil, Africa, and more.
Canary yellow diamonds can be found ion many regions the most valuable come from South Africa.
Diamonds are normally found in kimberlite pipes, which are ancient volcanic rock formations found in specific regions of the world such as Africa, Russia, Canada, and Australia. These kimberlite pipes bring diamonds from the Earth's mantle to the surface through volcanic eruptions.
Some of the highest quality diamonds are found in mines located in countries like Russia, Botswana, Canada, and some regions of Australia. These areas are known to produce diamonds with exceptional clarity, color, and size due to the geologic conditions present there.
Diamonds are found in diamond mines that circulate around volcanic pipes: mined diamonds.As well, diamonds are found under water where the water has washed over volcanic pipes that contain diamonds: alluvial diamonds.
Diamonds are not found in a great many different places. Diamonds are not found floating in the ocean for example.
Diamonds are typically found in regions with specific geological conditions, such as old volcanic pipes or cratons where the high pressure and temperature necessary for diamond formation can occur. These conditions are not common worldwide, so diamonds are only found in certain areas where these geological processes have taken place.
Diamonds are mined from geologic rock formations containing the ore kimberlite. The "pipes", or ore lodes, are found worldwide, in places such as South Africa, India, and Australia. (see the related link).
Usually, diamonds are found on earth around volcanic pipes -- the core of diamond mines, or downstream from volcanic pipes -- alluvial diamonds -- when flowing water rolls diamond stones away from the pipes where they erupted to the earth's surface.
Diamond 'connoisseurs' prefer Type IIa diamonds, which are found in India and in South Africa. Type IIa diamonds are the purest form of diamond, containing zero impurities. From Wikipedia: "Type IIa diamonds make up 1-2% of all natural diamonds (1.8% of gem diamonds). These diamonds are almost or entirely devoid of impurities, and consequently are usually colourless and have the highest thermal conductivity."
Diamonds are commonly found in volcanic pipes.
No, no natural diamonds are found in New Zealand.
Diamonds are primarily found in volcanic pipes known as kimberlite, which are located in countries like Russia, Botswana, Canada, and Australia. They can also be mined from alluvial deposits, where they have been eroded and transported by water, in regions such as the Democratic Republic of the Congo and Namibia. Additionally, synthetic diamonds are produced in laboratories worldwide, expanding the sources of diamonds beyond natural deposits.
