Ever Wondered What the Deepest Hole We Can Possibly Dig is Used for? On This Occasion, We Will Show You How Fair Diamonds Are Mined, Processed, Extracted, Cut, and Polished to Perfection. Welcome to Botswana, Africa: the second-largest producer of diamonds in the world (1.Russia). Natural diamonds have ages between 1 billion and 3.5 billion years. They were formed at depths between 150 and 250 kilometers / 93 and 155 miles in the Earth’s mantle, and some even deeper. Rough diamonds were carried to the surface in volcanic eruptions and deposited in igneous rocks – kimberlites which are found in Jwaneng. Jwaneng Mine is the richest diamond mine in the world by value. The first step to mine these precious gemstones is drilling and blasting. Safety is ensured by highly qualified engineers and workers, who can set an example to the whole world, not just Africa. Once the dust has settled, massive trucks roll in and haul diamond containing kimberlite ore out of the pit. Road construction, water management and follow-up maintenance is crucial for a smooth and profitable mining operation. The first step in kimberlite ore processing is crushing and here the diamonds enter a very long pipeline all the way to the final recovery. Diamonds have a higher density than the host rock. Scrubbing is used to wash and break down clay lumps present in the crushed ore. Once the ore is screened it is mixed in a slurry which is called dense medium separation (Concentrate), where diamonds due to their density sink to the bottom. The last step is the recovery of diamonds and happens in a fully automated, 16-story building called “The Aquarium”. The Diamonds fluoresce when irradiated with x-rays and here technologically advanced machines exploit these properties. From recovery, the diamonds proceed to the sorting and grading process. With over 12,000 different categories of diamonds, it takes a trained eye and many years of experience to determine each diamond’s value. You are watching the transformation process of the 302.37 carats Graff Lesedi La Rona, the largest and most expensive diamond in the world (Square emerald cut diamond that is). It was cut from the largest rough diamond (1,109 carats) discovered in 100 years in Botswana, and 66 other satellite diamonds were made out of it. The project lasted 18 months including planning, cutting, and polishing the rough diamonds using pioneering technologies.
