Formation Process
Carbon Source
Pure carbon buried 90-120 miles deep in Earth's mantle
Extreme Conditions
Temperatures of 2,000°F and pressure 725,000 psi
Crystallization
Carbon atoms arrange in crystal structure over 1-3 billion years
Volcanic Transport
Carried to surface by deep-source volcanic eruptions
Mining Locations
Major Sources
Russia, Botswana, Canada, Australia, South Africa, Democratic Republic of Congo
Mining Methods
Open-pit, underground, alluvial (riverbed), marine mining
Production
142 million carats annually, 90% used for industrial purposes
Natural Diamond Characteristics
Natural diamonds have unique properties that distinguish them from synthetic alternatives.
Unique Identity
Each natural diamond has unique internal characteristics and inclusions, like a fingerprint
Natural Inclusions
Natural minerals and fractures trapped during formation create unique patterns
Age
Most natural diamonds are 1-3 billion years old, formed deep within Earth
Geographic Origin

Natural Color
Colors come from trace elements and natural radiation exposure
Crystal Structure
Perfect cubic crystal structure gives diamonds their exceptional hardness
