- ‘The names of the ores of copper point to gentle Venus qualities: azurite, malachite, turquoise, chalcopyrite and peacock ore.’
- ‘Often, the powdery azurite encloses a small grain of cuprite, forming a blue halo that disperses into the siltstone.’

- ‘A frequently used mineral source of blue was azurite, a copper carbonate which was called lapis armenius as it originally came from Armenia.’
- ‘However, collecting in the pits has yielded beautiful microcrystals of azurite and malachite on quartz.’
- ‘Good nodular masses of azurite, some of which contain bladed crystals to 5 cm, occur in the Chingola mine, Zambia.’
- ‘For digital photography, SoLux bulbs are perfect, yielding accurate rendition of difficult-to-photograph minerals such as dioptase and azurite.’
- ‘The most common nodules are pure azurite in radially fibrous masses that exhibit a peculiar satiny sheen or chatoyancy on broken surfaces.’
- ‘Only a handful of high-quality azurite in equant blocky crystals to 4 cm have been found in these pockets so far.’
- ‘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.’
