LOMA Goldschmied

LOMA Goldschmied is a small goldsmith workshop on Kuttelgasse, a narrow lane in Zürich's old town just off the Niederdorf quarter. The atelier is run by Marco Mauchle and Florian Bissig, two goldsmiths who met while training for the trade and who spent years working together at the well-known Zürich house Steinlin before taking over its old-town workshop under the new name LOMA in 2025. For a newcomer to Zürich shopping for an engagement ring, that history matters more than the young company registration date suggests: the hands on the bench have made, reworked, and restored jewellery in this same corner of the old town for years, even though LOMA itself is a recent legal entity.

What you get

LOMA's core offer for anyone planning a ring is a custom commission, which the atelier calls a Spezialanfertigung. The workshop lays the process out in 5 stages on its own site: an initial consultation to talk through the idea, a visualisation stage where the atelier produces design drafts so a client can see roughly how the finished piece will look, a physical prototype so proportions and the way a ring sits on the hand can be checked and refined, the final production in the chosen metal, and delivery of the finished piece. Nothing on the site states how long that process takes or what it costs, so anyone planning a proposal timeline from abroad should ask directly rather than assume a Swiss atelier's schedule matches expectations from home.

The workshop's services page is explicit that this covers engagement ring consultations by name, alongside repairs and reworking. If a client already owns a stone, an heirloom band, or a ring inherited from a parent or grandparent that no longer fits their taste, LOMA describes sitting down with the client and planning together how to turn that existing piece into something new. Straightforward repairs sit alongside that work: refreshing a tired piece, replacing a stone, or a full restoration back to its original condition. The atelier's values page also states that it stays available after a piece is delivered for adjustments, repairs, and general care of the item, which matters for anyone who buys a ring in Zürich and later needs it resized or serviced, including someone who has since moved away.

What stands out

Two things separate LOMA from a shopfront that simply sells rings off a tray. First, a client speaks directly to the goldsmith who will make the piece rather than to sales staff, something the atelier states plainly about its own way of working. Second, LOMA says it works with what it calls Ökogold, gold and other precious metals sourced through a closed recycling loop, and that it keeps long personal relationships with its gemstone dealers built on transparency and reliability, in its own words. Alongside traditional bench techniques, the workshop also uses 3D-CAD design, CNC milling, and rapid prototyping to plan a piece before it is made in metal, a practical way to show a client a realistic preview of a custom ring before committing to the final material.

LOMA also runs a small in-house jewellery line beyond bespoke commission work, organised into 6 named collections (Aura, Calado, Makura, Pala, Bambu, and Lumy) shown in a filterable catalog on its site. The catalog lists materials including white, rose, and yellow gold alongside ebony, mammoth, and horn, and stones ranging from diamond and sapphire to garnet, tourmaline, and moonstone. None of the current catalog pieces are marketed specifically as engagement rings, so this range reads more as a demonstration of the workshop's finishing quality than an off-the-shelf bridal selection. LOMA also partners with LILLY CLOU, a silver jewellery and accessories label run by Fabienne Sponagel, and points customers to it for a wider choice of silver bracelets, earrings, and gift pieces.

How it's organised

The workshop keeps old-town retail hours: Tuesday to Friday from 10 to 18, Saturday from 10 to 16, closed Sunday and Monday. The address is Kuttelgasse 15, in the 8001 postcode area of central Zürich, an easy walk from Bahnhofstrasse and the larger jewellery houses there. Contact runs through phone or email; the site itself is presented in German only, with no English version and no stated language capability, so an expat buyer who isn't confident in German should plan to call or write ahead and confirm the atelier can work with them in English before booking a consultation. That is a real gap for a tenant built around international and expat buyers, and it is the clearest caveat here.

How it compares

Against the Bahnhofstrasse houses that anchor this tenant's other categories, LOMA is a different kind of business entirely: a two-person atelier rather than a retail counter backed by a large brand. That means slower throughput and no walk-in stock of finished engagement rings to try on, but it also means the person designing a custom piece is the same person cutting and setting it, without a handoff to an outsourced workshop somewhere else. Against the other old-town goldsmiths in this category, LOMA's continuity from Steinlin gives it a working track record that a genuinely new atelier would lack, even though the LOMA name itself only appeared in 2025.

Who it suits

LOMA fits an expat or international buyer who already has a stone, a family ring, or a clear idea and wants a genuinely custom Zürich-made engagement ring rather than a boxed one, and who either has time in the city to sit through a multi-stage design process or is willing to coordinate the fittings by email. It suits someone comfortable arranging that process in German, or willing to confirm English support before booking. It suits less well a buyer who wants same-visit pricing transparency or a ring ready to walk out with, since neither is published on the site.

The verdict

LOMA earns its place in this category on the strength of what its two founders bring from their years at Steinlin, now offered under their own name: a genuine custom-commission process, honest reworking of existing pieces, in-house repairs, and materials the atelier says it sources with some care. The German-only site and the absence of published pricing or turnaround times are real gaps for an international buyer, worth closing by email before committing to a design, but they don't outweigh the appeal of working directly with the goldsmith making your ring, in a workshop that has quietly been doing this work in the same old-town corner for years.
