noun

Etymology: Borrowed from Portuguese carbonado (“carbonized”), probably from carbono (“carbon”) (currently only attested later than carbonado) + -ado (suffix forming adjectives from nouns meaning ‘something or someone who has suffered the action’). Carbono is borrowed from French carbone (“carbon”), from Latin carbō (“coal; charcoal”); for further derivation, see etymology 1.

  1. A dark, non-transparent, impure form of polycrystalline diamond (also containing graphite and amorphous carbon) used in drilling.

    At present, equal attention is paid to irregular fragments of a blackish or greyish colour, occasionally of considerable size, also yielded by the washings of diamandiferous sand, which formerly passed unregarded. These fragments are now carefully colected, and have acquired some considerable value in commerce, where they are known under the name of carbonado or carbon. […] An examination of these numerous varieties has made it evident that between carbonado of a simply micro-crystalline texture, and the diamond regularly crystallised in diaphanous octahedrons, there exists an uninterrupted series of intermediate conditions.

    Brazil's carbonadoes are indispensable today for the speedy cutting of hard rubber, bakelite and fiber compounds. Their absolute precision is especially valuable in turning such instruments as high-power telescopes and microscope tubes.

verb

Etymology: The noun is derived from Spanish carbonada (“carbonized”) (from carbonar (“to carbonize”)) + -ado (suffix forming past participles of regular verbs ending in -ar). Carbonada appears to have been modelled after Italian carbonata (“coal pile; stew of beef in red wine”), from carbone (“coal; charcoal”) (from Latin carbō (“coal; charcoal”), from Proto-Indo-European *ker- (“to burn”)) + -ata. The verb is derived from the noun.
