Since 1989
A family legacy, handcrafted.
What began as one man's vision to create emotional connections through jewelry has grown into a family tradition — worn by clients around the world.

The Founder
Iakov, and a love that shaped a maison.
In 1989, in the diamond district of Antwerp, Iakov set out to make jewelry the way it was meant to be made: patiently, honestly, by hand. What began as the founder's obsession with craftsmanship became a love story — first with Nunu, his wife, then with the generations of clients who chose MAISON IN to mark the most important days of their lives.
The name MAISON IN carries those two initials: I for Iakov, the founder, and N for Nunu, the love beside him. What Iakov built at the bench, they shaped as a family — and every piece that leaves our atelier still carries that same spirit of love, precision and craft.
For over three decades, we've crafted exceptional jewelry that blends contemporary style with luxurious craftsmanship. Each piece tells a story, carries meaning, and becomes part of a family's legacy — passed down through generations as treasured heirlooms.
"We don't just make jewelry — we create emotional connections between people, memories, and moments. When someone wears our pieces, they carry a story."
Today, his children continue his legacy at the bench and behind the counter. Every piece that leaves the atelier carries forward the same conviction: that the greatest luxury is time, and the greatest gift is something that lasts.
The DNA
What we believe in.
Handmade in Antwerp
Every piece is designed, set and polished at our bench in the diamond district — never outsourced.
Family, not factory
MAISON IN is a family workshop. The people who make your jewelry are the people who greet you.
Made to be worn
We design for a lifetime — pieces heavy enough to feel, light enough to live in every day.
