A diamond cluster pendant/brooch, centred with an old-cut diamond of yellow tint in pinched collet setting, within an openwork border of smaller old-cut diamonds, to a crescent-shaped surround of graduated similarly-cut diamonds, spaced by lasque-cut diamond points, with detachable diamond set pendant bale and detachable brooch fitting, accompanied by Wartski retailer's case and purchase receipt dated 1969, and an unassociated curb-link chain, principal diamond weight approximately 2.35ct, remaining total diamond weight approximately 2.80ct, total length 3.3cm
The principal diamond draws a pronounced yellow tint and has strong bluish fluorescence under LWUV, with scattered small nicks, chips and naturals to the girdle. The outline is off-round but faceting is fairly symmetrical. Estimated SI1 to SI2 clarity, assessed mounted. Principal diamond dimensions approximately 8.9mm to 9.2mm diameter x 4.75mm depth. The bordering old-cut diamonds are bright and lively with slightly variable clarity, some stones with chips, nicks and surface-reaching fractures. These diamonds have estimated H to K colour and VS1 to P2 clarity, assessed mounted (those with chips/fractures have P2 clarity) and graduate from approximately 0.23ct to 0.01ct in size. Lasque-cut diamonds have a typically greyish, fractured appearance.
It is possible that the outer crescent-shaped border has been later added to the central cluster setting but both appear to be of a similar age, which is likely to be late 19th/early 20th century. The settings are probably a gold/silver combination, but are untested as such, and have considerable dark tarnishing/fire staining. The mount has surface wear throughout, with slight thinning to the edges of some settings. Width of mount 2.65cm. The detachable brooch fitting has a fairly modern visor clasp that functions and is accompanied by a screwdriver. Gross weight of pendant/brooch (including fittings) approximately 8.6gm. The chain is untested for metal standard, gross weight approximately 2.7gm, length 51.5cm.
