Ruby

A ruby is a pink to blood-red colored gemstone, a variety of the mineral corundum (aluminium oxide). The red color is caused mainly by the presence of the element chromium. Its name comes from ruber, Latin for red. Other varieties of gem-quality corundum are called sapphires. The ruby is considered one of the four precious stones, together with the sapphire, the emerald, and the diamond.

    Thy great leaves enfold
    The ancient beards, the helms of ruby and gold
    Of the crowned Magi; and the king whose eyes
    Saw the Pierced Hands and Rood of elder rise
    In Druid vapour and make the torches dim....
    William Butler Yeats (1865–1939)

    Its quick silver bell beating, beating
    And down the dark one ruby flare
    Pulsing out red light like an artery,
    Karl Shapiro (b. 1913)

    It is better to be looked over than overlooked.
