A small atelier
with a long memory

One piece at a time, for one person at a time — made and remembered by hand in The Hague.

We believe in more than delivering fine jewelry — we deliver the experience of making it with you. A world of elegance where transparency, quality and personal service come first.

XLVIII & Co. is a custom fine-jewelry house based in The Hague, serving a worldwide clientele who trust us to bring their visions to life. Our jewelry is not merely an accessory — it's a manifestation of our dedication to design, detail, diamond quality and gold craftsmanship. Every piece is made one at a time, for one person.

What we stand for

Our mission & values

Listen first

We start from your idea, not our catalogue. The design follows the story you're trying to tell.

GIA standards

Every stone is graded to strict GIA standards and fully traceable — quality and authenticity you can verify.

Made by hand

Cut, set and finished in our own atelier — so the hand that makes your piece is the one you can talk to.

Ethically sourced
Traceable from mine to masterpiece
We source raw diamonds exclusively from three of the world's most reputable mines — Rio Tinto, Arctic Canadian Diamond Company and Okavango Diamond Company. We don't trade raw diamonds; every stone is cut and polished in our own facility so its journey is documented end to end.
