Type of jewel: Vintage antique diamond inline ring Condition: very good Country of origin: France and/or Belgium (see explanation below in the text) Style: Vintage antique Era: ca. 1840 Material: 18K red gold and details in 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. Diamond(s): Seven 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: Remains of what we think is the control mark that represents a horse’s head and was in use in Belgium from 1831 and in France from about 1838.

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.
