This one-of-a-kind chain extender began life as an Art Deco brooch and has been thoughtfully repurposed into a striking, highly versatile piece that brings antique brilliance to any modern stack.
Crafted platinum (front) and 18-carat gold (back), the elongated diamond bar showcases 22 old-cut diamonds totalling approximately 0.80-1.00 carat, with the largest measuring around 3mm (approx. 0.13ct). These beautifully hand-cut stones display natural carbon inclusions under close inspection, a charming hallmark of their billion-year formation, and offer a captivating sparkle that stands out even in low light.
A partially faded hallmark on the bar suggests the French dog-head platinum stamp, though time has softened the detail. The 18ct gold French swivel dog clip is clearly marked with the French eagle head, alongside another partially visible maker’s mark on the bail.
Measuring 4 inches in total length, with the diamond bar sitting at 5.5mm at its widest point, and fitted with an 18mm swivel clip, this extender is the perfect way to add drama, length, or functionality to your favourite chains and pendants. The warm gold tones paired with the icy clarity of platinum and antique diamonds create a sophisticated contrast that elevates any look. The piece remains in excellent antique condition.
This exceptional Art Deco conversion is truly a one-off - rich in history, craftsmanship, and style.
