Antique 18K yellow gold ring with silver details, 2 g total weight, set circa 1900 with eight rose-cut diamonds, two natural rubies (approx. 0.20 ct) and one cultured pearl, unbranded, no laboratory report, size EU56 / US7½.
Description from the seller
Type of jewel: Vintage antique diamond and ruby ring set with a pearl
Condition: In well-preserved condition, especially given the jewel`s age.
Style: Vintage antique
Era: ca. 1900
Material: 18K yellow gold and details in silver (touchstone tested)
Diamond(s): Eight 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.
Precious stone(s): Two natural rubieswith an estimated weight of ± 0.20ct.
One cultured pearl
- It is common practice to treat gemstones to enhance their clarity or colour. This item has not been tested for such treatments.
- All gemstone weights are approximate, as the stones are not removed from their settings to preserve the integrity of the piece.
Birth and month stones: Diamond is the birthstone (or month stone) for April, Ruby is the birthstone (or month stone) for July, and Pearl is the birthstone (or month stone) for June.
Hallmarks: No trace.
Dimensions: band width top of ring 1,17 cm (0,46 inch) - See picture with a ruler in cm and inches
Weight: 2,00 gram (1,29 dwt)
Ring size: EU-56 & 17¾, USA-7½, UK-O½
Ring sizes are professionally measured and rounded to the nearest millimetre; slight variations are standard and do not affect wear.
Adin reference Nº: 26089-0358
