THE MAISON

Personal expression.
Considered beauty.

Founded in Los Angeles in March 2023 by Su Wiśniowiecka, ANTONINA brings a personal perspective to bespoke fine jewelry.

THE NAME. THE BEGINNING.

A name held close.
A vision of her own.

ANTONINA takes its name from Maria Antonina, Su’s mother. Her work in art curation and European cultural exchange, and her attention to painting, architecture and artistic detail, helped shape Su’s interest in beauty and personal expression.

That influence became the starting point for a new business of Su’s own. She founded ANTONINA to bring a personal approach to fine jewelry: a conversation about the wearer, translated into the character of a stone, a considered silhouette and the details of a bespoke piece.

The Maison’s name honours a personal influence; its direction is Su’s own. Her role connects that creative intention with the organisation, specialist collaboration and care required to deliver a private commission.

THE DEVELOPMENT OF THE MAISON

From an idea
to a private commission.

A Los Angeles business built around individual clients and a clear, considered process.

SECOND HALF OF 2022

Laying the foundations

Su began developing the brand’s positioning, studying client needs, the bespoke process and the cost structure of a jewelry business. During this period she started establishing working relationships with professional designers, gemstone specialists and independent workshops.

MARCH 2023

ANTONINA is founded

ANTONINA Fine Jewelry was established in Los Angeles, with Su as Founder & Managing Director. The business centred on bespoke fine jewelry, engagement and commemorative pieces, and the redesign of existing jewelry.

THE MAISON TODAY

A personal way of working

The Maison operates through private appointments and made-to-order commissions, alongside small-scale pieces. Consultation, budget confirmation, design proposals, stone selection, making, delivery and aftercare form one connected service.

Design and budget guide the choice of 18-karat gold, platinum, diamonds and coloured gemstones. Su oversees brand direction, business planning, financial supervision and important client and professional relationships, supported by specialist responsibilities across design, gemstone procurement and workshop delivery.

WHY BESPOKE

Because the meaning
comes first.

A private commission makes room for something that already matters: a relationship, a milestone, a colour or a jewel carried through the family. The purpose is to give that meaning an individual form.

ANTONINA’s approach begins with listening and develops through a practical sequence of decisions. The client’s preferences, intended wear, materials, budget and schedule are considered together, so that personal expression and careful execution remain part of the same process.
