Explore natural diamonds, Earth's ancient geological marvels formed deep within the mantle over billions of years. This section covers their unique formation,...
Natural diamonds are minerals composed of pure carbon, formed deep within the Earth's mantle under immense heat and pressure over billions of years. They are then brought to the surface through volcanic activity.
Natural diamonds are created by geological processes within the Earth, while lab-grown diamonds are synthesized by humans using advanced technological processes that mimic natural conditions. Chemically and structurally, they are identical, but their origins differ significantly.
A natural diamond's value is primarily determined by the '4 Cs': Carat (weight), Cut (shape and facets), Color (ranging from colorless to light yellow), and Clarity (presence or absence of internal and external flaws). Rarity and market demand also play roles.
Natural diamonds are found in primary deposits (kimberlite and lamproite pipes) and secondary alluvial deposits. Major diamond-producing countries include Russia, Botswana, Canada, Australia, South Africa, and Angola.
