Citrine, the translucent, pale yellow to brownish orange variety of quartz, is quite rare in nature. In the days before modern gemology, it was often confused with topaz. Citrine’s striking colour, plus the durability and affordability it shares with most other quartzes, makes it the top-selling yellow-to-orange gem. It’s an attractive alternative not only for topaz, but also for yellow sapphire. The finest citrine colour is a saturated yellow to reddish orange, free of brown tints. Along with topaz, citrine is the birthstone for November and is also recognized as the gem that commemorates the 13th anniversary.
