-Diamond endstones were said to give the chronometers the precision and longevity needed to keep time. The diamond's in the 18th century chronometers most likely produced through colonial extraction in Brazil reliant on slave labor. By the 19th century the diamond's most likely extracted from the Big Hole in Kimberley South Africa, an underground open mine dug by hand by 10,000 Black workers who dug the Big Hole and laboured to extract diamonds from the volcanic rock.
