This sparkling Amethyst gemstone is the birthstone for February. This 6mm faceted stone features a lightly patterned, 14 Karat Gold Filled setting that wraps around only the edge of the stone, revealing 95% of the stone. This allows as much light as possible to shine through to highlight the stone's full sparkle. Gold Filled is more durable and gold plated, and it means that the top layer gold is at least 5% of the total metal. In this case, the top layer is 14 Karat Gold. All of the Sparkle Charms are made with synthetic gemstones. That means they have the same chemical and physical properties of the naturally mined gemstones, but they are created in a laboratory.
