Type of jewel: Vintage antique diamond brooch Condition: In a good state, particularly considering the jewel's age. Style: Vintage antique Era: ca. 1870 Material: 18K gold backed silver (touchstone tested) Technique: The rose cuts are set on foil. This is a ancient technique that was used to bring the lustre of the diamonds to its best quality. This is being done by placing in the closed mounting under the diamond a highly polished cone of silver foil. Extra information: This is what in our trade is called "a marriage". This means that parts of several jewels, somewhere in their life, where "married" together into this jewel. Diamond(s): Five senaille and rose cuts. A senaille is a simplified rose cut diamond, a small diamond chip with perhaps a few polished facets. We do not have the weight of these diamonds which is normal in our trade when it comes to senailles or rose cuts. All diamonds in our vintage and antique jewellery are verified by the IJGC-lab to confirm whether they are natural or lab-grown. We do not offer any pieces with lab-grown diamonds. Thus, we assure that all diamonds in this jewel are 100% natural. Birth and month stones: Diamond is the birthstone (or month stone) for April. Hallmarks: No trace.

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.
