Type of jewel: Vintage 1920s Art Deco diamond and sapphire ring Condition: very good Style: Vintage 1920's Art Deco Style characteristics: Abstract motives and geometrical forms are quite typical for the Art Deco period. Era: ca. 1920 Material: 18K yellow gold and details in platinum (touchstone tested) Diamond(s): Four senaille 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. 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. Precious stone(s): One sapphire (lab produced, also called Verneuil sapphire) with an estimated weight of ± 3.00 ct. The weight of stones are approximate since the stones were not removed from their mounts, this to preserve the integrity of the setting.

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.
