AI-assisted summary
Description from the seller
Type of jewel: Vintage 1950s 18K white gold diamond engagement ring
Condition: In well-preserved condition, especially given the jewel`s age.
Style: Vintage
Era: ca. 1950
Material: 18K white gold (touchstone tested)
Diamond(s): One One large rose-cut diamond. As is often the case with rose-cut diamonds, its weight is not known. Judging by its outer dimensions, it is comparable in spread to a brilliant-cut diamond of approximately 0.45 ct.
- 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.
Birth and month stones: Diamond is the birthstone (or month stone) for April.
Hallmarks: "0750" suggesting 18K gold
Dimensions: band width top of ring 1,06 cm (0,42 inch) - See picture with a ruler in cm and inches
Weight: 3,20 gram (2,06 dwt)
Ring size: EU-54 & 17¼, USA-6¾, UK-N
Ring sizes are professionally measured and rounded to the nearest millimetre; slight variations are standard and do not affect wear.
