About this piece
Five calibrated sapphires set flush into a solid 9ct gold band, so nothing stands proud of the metal. Total carat weight across the five stones is 0.60 ct. At 2.8 g of gold the band is well over the 1 g statutory exemption and carries a full UK hallmark: sponsor's mark, 375 millesimal fineness and the London Assay Office town mark. The marks are photographed in the gallery at magnification.
Total carat weight across all 5 stones: 0.60 ct. The wear grade shown for the piece as a whole is daily, because a piece is only as forgiving as its softest stone.
