Geometric jewels in gold, onyx and emerald — drawn from the architecture of 1925 and made, one piece at a time, in our atelier.

Every piece starts as a stepped silhouette on graph paper. Stones are cut to fit the geometry — never the other way round.
Emerald · 18k GoldA fan of baguette diamonds around a step-cut emerald.
$12,400
Onyx · 18k GoldA miniature skyline, tiered in black and gold.
$6,850
Diamonds · 18k GoldSeven rays, mirrored — symmetry you can feel.
$4,200
Onyx · 18k GoldA bold band of repeating chevrons in gold and onyx.
$8,900A one-hour sitting. We sketch three stepped silhouettes around your stone, your budget, your hand.
Four to six weeks at the bench. You receive two progress photographs — never more, never staged.
Presented in the black lacquer case, with a hand-signed certificate and lifetime care.
Most rings and cuffs, yes — within two sizes, by hand, in the atelier. Necklaces are made to your measured length from the start.
Emeralds and diamonds are sourced through two long-standing dealers and cut to our geometry. Every stone arrives with its certificate.
Warm water, mild soap, a soft cloth. Never ultrasonic on onyx. Bring it in once a year and we clean and inspect it free, for life.
