Diamonds are naturally occurring gemstones made of pure carbon arranged in a crystal structure. They are the hardest known natural material on Earth and are highly valued for their brilliance, durability, and rarity.
📍 Where are Diamonds Found?
Kimberlite pipes & volcanic rocks: Primary sources where diamonds form deep underground.
Alluvial deposits (riverbeds, gravel, beaches): Diamonds carried by erosion and water flow.
Major producers: Botswana, South Africa, Russia, Angola, DR Congo, Canada.
⚖️ Characteristics of Diamonds
Hardness: 10 on Mohs scale (hardest natural substance).
Color: Ranges from clear/white to fancy colors (blue, pink, yellow, green).
Clarity: Presence of inclusions or flaws affects value.
Cut: Determines brilliance and sparkle.
Carat weight: Standard unit for measuring size and weight.
🔍 How are Diamonds Mined & Processed?
Open-pit & underground mining (for kimberlite).
Alluvial mining (collecting from rivers and gravel).
Marine mining (offshore dredging).
Sorting & grading: Diamonds are sorted by size, quality, and use (gem vs. industrial).
Industrial applications: Cutting, grinding, drilling due to extreme hardness.
Investment: Some rare diamonds are held as alternative assets.
Technology: High-performance electronics, thermal conductors, and medical tools.
⚠️ Key Considerations
Conflict Diamonds (Blood Diamonds): Diamonds mined in war zones and sold illegally to fund conflicts. Reputable dealers follow the Kimberley Process to certify conflict-free diamonds.
Synthetic (Lab-grown) Diamonds: Increasingly popular; chemically identical but more affordable and ethical.
