Abstract

A sorting apparatus (100) for classifying candidate rough gemstones in aggregate material the apparatus comprising: a transport system (102) for individually transporting a stone from the aggregate material to at least one measurement location; a measurement system (104) configured to determine at the at least one measurement location one or more of: whether the stone comprises diamond material whether the stone comprises boart and the shape of the stone; the apparatus further comprising a dispenser system (106) configured to dispense the stone from the transport system to one of a plurality of locations in dependence on the determination of the measuring system.
