Rutile is named after Latin “rutilas” – golden red, alluding to its common colour, especially in transmitted light.
Golden-coloured rutile typically occurs in a slender acicular form. The small needles of rutile found in gems cause an optical phenomenon known as asterism. Asterated gems are known as “star” gems (Star sapphire, Star rubies, etc.).
