Type of jewel: Vintage antique diamond pendant with nice quality cut rose cut diamonds Condition: In well preserved condition, especially given the jewel’s age. The piece appears to have begun life as another jewel and was later converted into a pendant. The quality of the rose cut diamonds is exceptionally fine for a jewel of its period. The stones are set with notable care, combining differing shapes such as round and pear shaped examples in a balanced, symmetrical arrangement. High domed rose cut diamonds are used throughout, even for the smallest stones. Style: Vintage antique Era: ca. 1830 Material: 18K yellow gold and silver (touchstone tested) Technique: The rose cuts are set on foil. This is a ancient technique that was used to bring the lustre of the diamonds to its best quality. This is being done by placing in the closed mounting under the diamond a highly polished cone of silver foil. Diamond(s): 38 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. Birth and month stones: Diamond is the birthstone (or month stone) for April. Hallmarks: No trace.
