  • [mass noun] A blue mineral consisting of basic copper carbonate. It occurs as blue prisms or crystal masses, typically with malachite.

    • ‘A frequently used mineral source of blue was azurite, a copper carbonate which was called lapis armenius as it originally came from Armenia.’
    • ‘Microcrystals of azurite and goethite and a small number of microcrystals of chalcocite were also recovered.’
    • ‘Sometimes the aikinite is altered, and fractures in the surrounding quartz are filled with thin blue and green films of azurite and malachite formed from the copper liberated by the aikinite.’
    • ‘For instance, azurite, chrysocolla, and turquoise bring to mind vivid images of various shades of blue.’
    • ‘In some fractures bordering the clay seams, azurite and malachite occur as masses of alternating, crudely parallel bands.’
    • ‘However, collecting in the pits has yielded beautiful microcrystals of azurite and malachite on quartz.’
    • ‘For digital photography, SoLux bulbs are perfect, yielding accurate rendition of difficult-to-photograph minerals such as dioptase and azurite.’
    • ‘Good nodular masses of azurite, some of which contain bladed crystals to 5 cm, occur in the Chingola mine, Zambia.’
    • ‘The most common nodules are pure azurite in radially fibrous masses that exhibit a peculiar satiny sheen or chatoyancy on broken surfaces.’
    • ‘Locally stalactitic malachite, occasionally associated with well-crystallized azurite, occurred in the copper ores at Corocoro, Bolivia.’
    • ‘Associated minerals are olivenite, chalcophyllite, clinoclase, comwallite, strashimirite, malachite, azurite, and cuprite.’
    • ‘Often, the powdery azurite encloses a small grain of cuprite, forming a blue halo that disperses into the siltstone.’
    • ‘Associated minerals are azurite, quartz, plancheite, cerussite, and mottramite.’
    • ‘Many of the world's finest specimens of native copper, azurite, malachite, atacamite, and a host of other minerals originated in this manner.’
    • ‘The names of the ores of copper point to gentle Venus qualities: azurite, malachite, turquoise, chalcopyrite and peacock ore.’
    • ‘So far azurite, malachite, and cerussite have been found.’
    • ‘But if you are photographing a dark mineral such as azurite, the camera will lighten the exposure in an attempt to yield a medium value, making the image overexposed.’
    • ‘Only a handful of high-quality azurite in equant blocky crystals to 4 cm have been found in these pockets so far.’
    • ‘These contain veins of supergene copper minerals, mostly azurite and malachite.’
    • ‘The result can be some of our most spectacular minerals, including azurite, malachite, smithsonite, wulfenite, pyromorphite, and mimetite.’
