A timeless ICONS piece centred around an antique old European cut diamond repurposed from a Victorian era pendant, approximately 0.30ct, of J/K colour and SI1 clarity — eye clean, with subtle carbon deposits visible under magnification, a natural trace of its billion-year formation.
The diamond is set within its original platinum milgrain setting, retained and carefully integrated into an antique trombone link. The soft sparkle and classic proportions of the old European cut make this an effortlessly wearable and versatile piece.
Constructed entirely from antique 18ct gold components, with all links stamped crown “18”, including a sequence of oval and round links sourced over time and thoughtfully combined. A small newly made o-ring has been added to connect the antique dog clip, with all other elements remaining original.
Finished with an antique swivel dog clip clasp, this piece is designed as a signature extender or connector to elevate and reconfigure your chains. Clasp customisation or additions can be arranged on request (additional cost).
A one-of-a-kind ICONS design.
