Type of jewel: Genuine vintage antique Dutch rose cut diamonds ring Condition: In a good state, particularly considering the jewel's age. Country of origin: Netherlands Style: Vintage antique Era: ca. 1880 Material: 14K yellow 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): 41 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: The Dutch control mark for old Dutch jewelry that was brought to the essay office to check. This hallmark was in use since 1906.

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.
