Type of jewel: Vintage Fifties 18K white gold and platinum diamond Retro ring Condition: very good Country of origin: Belgium Style: Vintage 1950's Retro Fifties Era: ca. 1950 Material: 18K white and platinum (touchstone tested) Diamond(s): One brilliant cut with an estimated weight of ± 0.21ct. (colour and clarity: H/J, vs/si). 24 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 diamond weights, color grades and clarity are approximate since the stones were not removed from their mounts to preserve the integrity of the setting. 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: "0750" indicating 18K gold, "PT950" indicating 950/1000 platinum and a master mark from which the outer shape is in the shape of a barrel and was taken offically in use in Belgium since 1952 (but was already used before that date).

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.
