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.

    Lat me the dead look on;
    Wi’ cherry cheeks and ruby lips
    She lay an’ smil’d on him.

    An’ ae glass o’ your wine,
    For I hae fasted for your sake
    These fully day [is] nine.

    And down the dark one ruby flare
    Pulsing out red light like an artery,
