Please Note
All my items have a history, with many being older, vintage or antique. This piece isn't new, so anticipate signs of wear like slight bends in links, surface wear on gold, and stone scuffs. Expect these characteristics when purchasing pre-loved jewellery. I'll provide detailed descriptions and condition statements to ensure transparency about any possible flaws, feel free to message me with any queries!
