Citrine is the yellow member of the quartz family and is 
prized for its golden to lemon yellow hues. Its coloring is
due to ferric iron. Unfortunately it has also been commonly
called Citrine Topaz , which is a misnomer as Topaz is a 
completely separate gem species from Citrine. Its name is 
from the old French citrin meaning yellow. 

Treatment: Commonly heat treated (permanent color)
