David Yurmans Exotic Stone collection is characterised by hand-selected colourful rare polished gemstones, each tells a story and exhibits the power of nature. Due to their natural compositions, the stones are available only in limited quantities, making each piece a one-of-a-kind creation. This Exotic Stone Tag Enhancer necklace from David Yurman features black onyx. The chain is sold separately. To ensure the shine and polish of your David Yurman piece, wash with a little non-bleach soapy water and wipe clean with a soft cloth.
