⁂ De Boodt, a physician from Bruges, 'made the first attempt at a systematic description of minerals, dividing the minerals into great and small, rare and common, hard and soft, combustible and incombustible, transparent and opaque...There are also tables of values of diamonds according to their size and a short description of the polishing of precious stones.'
