A greenish-blue mineral consisting of hydrated copper silicate, typically occurring as opaline crusts and masses.
- ‘For instance, azurite, chrysocolla, and turquoise bring to mind vivid images of various shades of blue.’
- ‘Typically, the gold was associated only with secondary iron oxides, although several locations produced attractive specimens with malachite and chrysocolla and, in one location, minor galena and cerussite.’
- ‘An unusual occurrence of dioptase associated with paramelaconite, atacamite, cuprite, chrysocolla, and plancheite is described in ore from the Algomah mine, Ontonagon County, Michigan.’
- ‘The highly fractured felsite is cemented by veinlets of chrysocolla and malachite with minor amounts of cuprite.’
- ‘It is found in association with cerussite, calcite, hemimorphite, aurichalcite, malachite, willemite, and chrysocolla.’
Late 16th century (in the Greek sense): from Latin, from Greek khrusokolla, denoting a mineral used in ancient times for soldering gold.
