This season, the COS jewellery designers were inspired by semi-precious stones and the ideology of their symbolism. This dainty pinky ring is made from gold-plated recycled brass and features an organic-cut setting that's punctuated with precisely cut smoky quartz and Tiger's Eye that will glisten as they catch the light. Brass is a versatile material that can be recycled numerous times without losing any of its properties Shell: 90% Recycled brass, 10% Semi precious stone. Excluding trims.
