Such pieces frequently bear marks of this tender care. Furthermore, we present our antique and vintage jewellery in its authentic state, refraining from removing scratches or applying rhodium plating to white gold items. Our priority is to preserve the genuine allure and history of each piece. However, as the new owner, you have the option to take it to a local goldsmith for a cosmetic refresh, should you choose.
