The 972 carats (194.4 g) Excelsior diamond, the largest found at the Jagersfontein Mine.The sixth-largest diamond in the world, the Jubilee, found at the Jagersfontein Mine.
Jagersfontein Mine/ˌjeɪɡərzˈfɒnteɪn/ was an open-pit mine in South Africa, located close to the town of Jagersfontein and about 110 kilometres (68 miles) south-west of Bloemfontein.[1][2] Since it was first established,[3][4] two of the ten biggest diamonds ever discovered, the Excelsior and the Reitz (now called the Jubilee), were mined from Jagersfontein.[2] The term "Jagers" has since been coined to denote the distinctive faint bluish tint of the gems from this mine.[5] Among geologists, Jagersfontein is known as a kimberlite pipe,[6] and a prime locality for mantle xenoliths, some of which are believed to have come from depths of 300–500 km (190–310 mi).[1]
It is the biggest hand-excavated hole in the world at 19.65 hectares (48.6 acres), slightly larger than the Big Hole of 17 ha (42 acres) in Kimberley, which had previously claimed the title.[7]
