Type of jewel: Vintage 1930s Art Deco diamond ring Condition: In well-preserved condition, especially given the jewel`s age. Style: Vintage 1930's Art Deco Style characteristics: Abstract motives and geometrical forms are quite typical for the Art Deco period. Era: ca. 1930 Material: 14K yellow gold and white gold (touchstone tested) Diamond(s): Eleven senaille and rose cuts. A senaille is a simplified rose cut diamond, a small diamond chip with perhaps a few polished facets. - We understand that private buyers may expect diamond weights to be provided, but in the case of rose-cut or senaille diamonds, this is simply not standard practice among industry professionals specialising in antique and vintage jewellery. Unlike brilliant-cut diamonds, where weight correlates with diameter, rose cuts vary in thickness, making weight estimation impossible once set. Providing such figures could lead to unnecessary debates, as rose-cut diamonds were traditionally valued for their visual effect rather than intrinsic worth. Even major auction houses like Sotheby’s and Christie’s rarely list their weight, except for exceptionally large stones, where diameter is often provided instead. - All diamonds, regardless of their size or shape, in our vintage and antique jewellery are verified as 100% natural by the IJGC laboratory. - We do not sell lab-grown (synthetic) diamonds. Birth and month stones: Diamond is the birthstone (or month stone) for April. Hallmarks: "585" suggesting 14K gold Dimensions: band width top of ring 1,25 cm (0,49 inch) - See picture with a ruler in cm and inches Weight: 2,80 gram (1,80 dwt) Ring size: EU-58 & 18½, USA-8¼, UK-Q Ring sizes are professionally measured and rounded to the nearest millimetre; slight variations are standard and do not affect wear.

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.
