  • A striking early 1900s ring with a lozenge shaped silhouette. The head of the ring is set with a sparkling transitional cut diamond of approximately 0.40ct on a backdrop of bespoke faceted onyx. The centre diamond is of excellent quality and condition, with bright white colour and fiery facets that catch your attention from across the room. This centre diamond is framed by rose cut diamonds at either end of the lozenge, set into contrasting white metal that melts into the black of the onyx.


    This exceptional piece is finished with a trident of yellow gold to the shoulders, which leads to a classic gold shank. Offered in excellent overall condition, the only wear to note is some tarnishing to the metal and subtle evidence of a historical re-size to the rear.

      We offer a ring re-sizing service by our antique specialist for a small fee, starting at £40.

      Most of our rings can be resized, but if they can’t we will stipulate this in the description.

      As a rule we will only alter a ring by three UK sizes. If you would like to size a ring more than three UK sizes (either up or down) please contact us on a case by case basis and we will try and accommodate you as best as possible.

      We do not offer refunds on altered pieces, so please make sure you love your new piece before you purchase. 

      Sizing takes approximately 1-2 weeks.
