Where to find Diamond
Russia (Yakutia)
Significant producer of both gem and industrial diamonds, primarily from kimberlite pipes.
Botswana
World's leading producer by value, with large kimberlite pipe mines like Orapa and Jwaneng.
Democratic Republic of Congo
Major producer by volume, largely from alluvial deposits.
Australia (Argyle Mine)
Historically a major producer, particularly known for pink and red diamonds, though the mine ceased operations in 2020. Other Australian deposits exist.
Canada
Relatively new but significant producer, with several large kimberlite mines in the Northwest Territories and Nunavut.
South Africa
Historically the most famous diamond-producing country, with numerous kimberlite pipes and alluvial deposits.
Collecting tips
- Primary Deposits (Kimberlite/Lamproite Pipes). Diamonds are found within these igneous rocks. Prospecting involves identifying these specific rock types, often through geophysical surveys and indicator mineral sampling (e.g., pyrope garnet, ilmenite, chromite).
- Secondary Deposits (Alluvial/Placer). Diamonds, being dense and resistant to weathering, accumulate in river gravels, ancient riverbeds, and coastal marine terraces. Prospectors use panning, sluicing, and dredging techniques to recover them from these sediments.
- Safety Precautions. Diamond mining, especially artisanal mining, can be dangerous due to unstable ground, lack of proper equipment, and potential for conflict. Always prioritize safety and adhere to local regulations. For collectors, natural diamonds are not hazardous; however, industrial diamond dust can be an inhalation hazard if not properly managed.
Quick Check
- Color:
- Variable (colorless, yellow, brown, etc.)
- Luster:
- Adamantine
- Streak:
- Colorless (does not produce a streak on a streak plate due to its hardness)
