A saturated yellow to reddish-orange color free of brownish tints are prized in citrine. However, in the contemporary market, citrine’s most popular shade is an earthy hue (a deep brownish or reddish-orange). Considering natural citrine is rare, most of the citrine on the market is the effect of heat treatment, which causes some amethyst to turn color from pale purple to attractive yellow. It is the hue that determines the richness of the resulting citrine’s yellow. Color Light yellow to dark yellow, gold-brown Transparency Transparent, Translucent Citrine Clarity: C
