The rich golden color is what makes this Japanese Citrine so beautiful and vivid.  Here's some interesting citrine facts.  Citrine has been used ornamentally for thousands of years. In fact, in Ancient Greece, the stone was used as a decorative gem during the Hellenistic Age between 300 and 150 B.C. In addition, 17th century Scottish men used citrine on the handles of daggers and swords for decorative purposes. However, there is also record of entire sword handles that were crafted from citrine. More recently, citrine was particularly popular during the Art Deco era between World War I and World War II. During this time, movie stars wore oversized and elaborate citrine jewelry.
