All diamond weights, color grades and clarity are approximate since the stones were not removed from their mounts to preserve the integrity of the setting.

Thus, we assure that all diamonds in this jewel are 100% natural. Precious stone(s): Five sapphires.

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.
