Rich Madeira Citrine(1.35tcw, VS, Brazil) hand set in sterling silver studs. Citrine is one of the most valuable and popular gemstones in the quartz group. While many citrines on the market today are actually heated amethyst or smoky quartz, citrine does occur naturally in beautiful golden and brownish-orange hues. It's also possible that quartz crystals that grew naturally as amethyst or smoky quartz were turned into citrine by natural heat from nearby magma activity.Citrine has been used ornamentally on tools and in jewelry for thousands of years. In ancient Greece, the stone now known as citrine first gained popularity as a decorative gem during the Hellenistic Age, roughly between 300 and 150 B.C. In the 17th century, Scottish weapon makers used citrine to adorn dagger handles, sometimes even using a single large citrine crystal as the handle itself.
