Type of jewel: Vintage antique 18K red gold diamond and ruby ring

Condition: In well-preserved condition, especially given the jewel`s age.

Style: Vintage antique

Era: ca. 1900

Material: 18K red gold (touchstone tested)

Diamond(s): One rose cut.

- 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 rubies with an estimated weight of ± 0.12ct.

Two man-made half seed stone pearls

- 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: "18ct" suggesting 18K gold

Dimensions: band width top of ring 0,82 cm (0,32 inch) - See picture with a ruler in cm and inches

Weight: 2,00 gram (1,29 dwt)

Ring size: EU-52 & 16½, USA-6 , UK-L
Ring sizes are professionally measured and rounded to the nearest millimetre; slight variations are standard and do not affect wear.
