With its stunning sunlit hue, November's birthstone is a natural at giving the wearer a quick lift in mood and disposition. The citrine is said to improve friendships and ignite a creative fire in the souls of both artists and writers. It is also coveted as a "merchant's stone", as store and business owners throughout history have placed the buttery gemstone in their windows and cash register to attract and maintain their riches. Citrine also makes a lovely gift for a 4th wedding anniversary.
