The November birthstone, citrine, was once believed to promote mental clarity. Said clarity will be easy to achieve when you kick back and relax with citrine’s radiant orange glow—the perfect complement to autumn’s changing colors. The stone is made from quartz and gets its color from trace amounts of iron. It was often confused with topaz in acient times. Not only is Citrine the November birthstone, it is also the gemstone for the 30th anniversary.
