"The name Spinel is from the Latin word 'spina' which means spines. This refers to the stone's needle-like formations" (meanings.crystaljewelry.com).
"Spinel comes in a variety of colors, but the most commercially important are red and pink" (gia.edu).
"Spinels are allochromatic gemstones. This means that when the mineral is pure, it's colorless. Colors are derived only from the presence of trace elements acting as chromophores. Chromium, iron, and cobalt are the most common chromophores in spinel" (gemsociety.org).
