The amethyst stone displays a pale green color and a beautiful faceted cut that brings out its depth and sparkle. It's raised above the finger in a cathedral-style basket setting with open sides that allow light to filter through the stone. Petite diamond accents frame the stone on both sides, and a slender polished gold band completes the design. Green amethyst, an unusual green variety of quartz, is considered a collector's gemstone. Also known as Prasiolote, it is reputed to have healing properties that include strengthening the mind, emotions, and will in order to enhance prosperity. Green amethyst is a durable gemstone that holds up well to everyday wear.
