This raw Amethyst sterling silver plated necklace is a quick favorite in my book. She measures 21", the stone is large, measuring 2.50" wide and 2.25" in length, you'll see the Green Agate peeking through the top layer and has a smooth polished finish on the front. Over and above the physical properties and benefits of Amethyst, the stone's purple color is a natural tranquilizer. It is said to dispel rage, help manage fears, and anger and calm rage and anxiety. Other believed benefits of Amethyst include the ability to alleviate sadness, and grief and dissolve negativity.
