The photographs don't fully capture the true beauty of this stone—it's genuinely more stunning in person and on the skin. This Apatite gemstone features vibrant shades of deep ocean blues with earthy veining that shifts in natural light. Wire-wrapped in Argentium silver for a brilliant, tarnish-resistant finish that complements the stone's depth perfectly. Length: 16" Materials: Natural Teal Blue Apatite Smooth 10mm coin, Argentium Silver*, with a sterling silver lobster clasp. *Sterling silver is a classic alloy made of 92.5% silver and 7.5% copper. In contrast, Argentium silver contains a higher purity (usually 93.5% to 96% pure silver) and replaces most of the copper with germanium. This substitution results in a brighter white shine, superior tarnish resistance, and hypoallergenic properties.
