Quatrefoil
The Quatrefoil Collection
In Full Bloom, Forever
The bloom that never fades — rose gold and red brilliance, for ordinary days and the ones you'll remember.
Design & Craftsmanship
The Inspiration
The quatrefoil runs through Gothic tracery, Celtic knotwork and Renaissance parterres — four lobes inside a square, a shape that reads as both organic and strictly ordered.
That tension is the point. The motif feels grown rather than drawn, yet it obeys a rule you can state in one sentence.
When to Wear It
Quatrefoil works across the working week: flat-backed, low-snag, comfortable under a sleeve or a jacket lapel.
For formal occasions, wear the full pair — the four-lobe motif reads clearly at distance in a way small round studs do not.
