Blue stone is a generic mineral description commonly applied to a variety of minerals. Perhaps the most common reference is to the hydrated copper(II) sulfate mineral, chalcanthite. The name "blue stone" is also applicable to lazurite, the core constituent of lapis lazuli, a sulfide of sodium aluminium silicate in the sodalite group.
The term bluestone is also used for the dolerite stones at Stonehenge.

Famous quotes containing the words blue and/or stone:
“Mozart has the classic purity of light and the blue ocean; Beethoven the romantic grandeur which belongs to the storms of air and sea, and while the soul of Mozart seems to dwell on the ethereal peaks of Olympus, that of Beethoven climbs shuddering the storm-beaten sides of a Sinai. Blessed be they both! Each represents a moment of the ideal life, each does us good. Our love is due to both.”
—Henri-Frédéric Amiel (1821–1881)
“I can well conceive a man without hands, feet, head.... But I cannot conceive man without thought; he would be a stone or a brute.”
—Blaise Pascal (1623–1662)
