Effy 18ct White Gold Fancy Yellow Diamond Double Halo Ring 4.9g 750 Hallmarked

An Effy 18ct white gold ring set with a cushion shaped fancy yellow diamond at the centre, inside a double halo of round brilliant cut diamonds, the shoulders and the shank pave set with more. Effy's own logo is struck inside the band.

Hallmarks: this ring arrived with the maker's 18K and EFFY stamps and no UK hallmark, so we sent it to the Birmingham Assay Office ourselves. It came back struck with our registered sponsor's mark EEC, the fineness 750 for 18ct gold and the Birmingham anchor, on 9 September 2026. The full row is photographed on the listing beside the Effy logo. Read under a loupe here and photographed on the listing, mark by mark.

Measurements: UK size O 1/2, weighing 4.9g gross including the diamonds. Measured and weighed here, not copied from anywhere.

Condition: excellent, cleaned and polished before despatch.

Professionally cleaned and polished before despatch, supplied in a new Chapman gift case, and sent insured by Royal Mail Special Delivery.
