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.

“Lay down, lay down the bigly bier,
Lat me the dead look on;
Wi’ cherry cheeks and ruby lips
She lay an’ smil’d on him.

O ae sheave o’ your bread, true-love,
An’ ae glass o’ your wine,
For I hae fasted for your sake
These fully day [is] nine.”
—Anna Gordon Brown (1747–1810)
