Bold purple and creamy translucent white. How can you not love the perfectly parallel to one another lines of agate? A simplistic design means the perfect fit for both extravagant and easy going outfits. Set on 925 sterling silver. Although most people are unaware, most popular bright Agate colors like purple, electric or vibrant blue, pink and green are usually due to dyeing and while they will not "bleed" from wearing they are not usually natural. They do make a great choice for a statement piece nonetheless.
