At least eleven diamond quarries (called "garimpos" in Brazil), both active and inactive, were reported by Fernandes et al. (2014) in the valley of the Santo Inácio river between 8 and 28 km generally to the southeast of Coromandel. The geographic coordinates provided correspond to the largest site affected by quarrying operations visible on satellite imagery, but individual sites are spread out along the course of the river. The "Carneca I," discovered along the river in 1940 weighed 428 carats, and is the third largest diamond ever found in Brazil. Two other diamonds discovered in 1971 weighed just over 100 carats. These are the Charneca II and Charneca III, at 107 and 105 carats, respectively.
