By Ramon Cortes, Graduate Gemologist (GIA)
The Diamond, from the heart of the Earth to the center of power, follows carbon across six books, from its cosmic origin to the choices facing today’s diamond world.
Book I treats the diamond as a cosmic fact: the origin and abundance of carbon, the physics of diamond formation, the diamond window of the Earth’s mantle, the age of diamonds and their extraterrestrial cousins. Book II descends into the hidden stone: kimberlite and lamproite pipes, secondary and marine deposits, and the geopolitics of extraction. Book III turns to the hand of humankind: the rough diamond, the history and shapes of diamond cutting, its places, trades and tools. Book IV measures the invisible: inclusions, the 4 Cs, additional grading criteria, the physics of colored diamonds, rare optical varieties, and the laboratories and certificates that institutionalize expertise. Book V examines the desired stone: symbolism, high jewelry and the great houses, famous diamonds from the Koh-i-Noor to the Taylor-Burton, the figures who shaped this history, and its dark side of fraud and trafficking. Book VI confronts the irreversible present: the global trade, the Kimberley Process, environmental issues, laboratory-grown diamonds, blockchain traceability and the market’s contemporary trends.
