A jewelry item comprising a naturally occurring, deep-blue metamorphic rock and a precious metal. Typically, the stone is cut and polished, then affixed to a setting crafted from a lustrous, white-colored metal. Such adornments are often worn on a chain or cord around the neck.
These objects combine the perceived metaphysical properties of the gemstone with the aesthetic appeal of the metallic component. Historically, the rock has been associated with royalty, wisdom, and truth, while the metal provides durability, shine, and hypoallergenic qualities depending on its composition. This combination can result in a valued and visually striking accessory.
