A sensational antique diamond conversion chain, a masterpiece transformed from several watch chains into a breathtaking diamond necklace.  Crafted in 18-carat gold, this mixed-link chain features dazzling diamonds, coveted trombone chain links and chubby wide curb links.  Each link is solid gold (not hollow) and bears the hallmark of quality with a crown and "18" stamp for 18ct gold.  One of the trombone links bears the stamp for Chester and a faded date letter, believed to reference the year 1892.


The magnificence of this chain lies in its alternating diamond trombone links, some adorned with repurposed antique old cut diamonds (1.32cts) set in platinum on both sides and others encrusted with scatter-set round brilliant diamonds (1.18cts) - an astonishing 2.51cts of sparkling brilliance.  A truly breathtaking, one-of-a-kind piece.


Measuring 20.5 inches in length, this fantastic chain offers endless versatility. Whether worn with the diamond links prominently displayed at the front and centre, styled as a lariat, or adorned with your favourite charms and pendants attached to the bolt ring and swivel dog clip, this chain effortlessly elevates any ensemble.  Explore our product photos for styling inspiration.
