Citrine

Citrine was once the Rodney Dangerfield of the gem world. Due to its abundance, it would “get no respect,” as it were. In recent decades, this perception has changed, partly because earth-tone jewelry has come into vogue. Home shopping networks have also marketed the various shades of citrine aggressively, with catchy adjectives like “butterscotch” and “whiskey.” Apparently, this has worked. Citrine is now a modern alternative birthstone for November.

Mining actually yields very little citrine. The vast majority of citrine on the market is produced by heating smoky quartz (which produces light to medium yellows) and amethyst (which produces stronger yellows and orange-red to orangey brown shades). Natural stones usually occur in pale yellow colors, often with smoky tones.
