Goldschmied Bruno Troller

Bruno Troller runs his goldsmith atelier from Zugerstrasse 17, in the centre of Horgen, a lakeside town on the southern shore of Lake Zurich, part of the same lake-and-Oberland spread as the rest of this category rather than Zürich's old town or one of the city's own residential quarters. The site titles the business itself "Ihr Diamanten- und Schmuckspezialist," your diamond and jewelry specialist, and everything below that headline follows the same order: stones first, metalwork second. "Diamanten sind unsere Leidenschaft," the homepage says, diamonds are our passion, before it gets to goldsmithing at all. Switzerland's commercial register lists the legal entity behind the shop, Bruno Troller AG, as founded in 1983 and still active, with Bruno Troller himself named as its manager, which puts a specific, checkable figure behind the site's own claim to "langjähriges Wirken," years of accumulated work.

What you get

The pitch is consultation first. "Die Wünsche und Bedürfnisse eines jeden Kunden sind sehr persönlich. Unsere Beratung ist es auch," the site says, each customer's wishes are very personal, so is our advice. Troller frames the work around the customer's own ideas rather than a fixed collection, making pieces "nach eigenen Entwürfen und Vorstellungen des Kunden," to the atelier's own designs and the customer's own ideas, which suits a reader who already owns a stone (an inherited diamond, something bought elsewhere) and wants it sourced further, cut or reset rather than starting from a blank sketch. What separates this workshop from most single-name ateliers in this category is its "eigene kleine Steinschleiferei," its own small stone-cutting workshop, which the site says lets it grind rare minerals itself in combination with precious metals rather than sending stones out to a third party. Having its own stone-cutting bench in the same small operation as the metalwork is a genuine mark of a working atelier rather than a name badged onto pieces cast elsewhere, stated specifically rather than implied.

What stands out

Two Swiss business directories, search.ch and local.ch, independently list Goldschmied Troller at 5 out of 5 stars from 5 reviews, and both carry the same customer account. A review from June 2021 reads, "Seit mehr als 20 Jahren ist der Juwelier B.Troller unsere Adresse für Änderungen und Anfertigungen von Schmuck," for more than 20 years jeweler B. Troller has been our address for jewelry alterations and new pieces, adding that the prices are very reasonable. A second review, from September 2019, separately calls the service excellent and the prices fair. Neither is the business's own copy, and a customer relationship running past 20 years lines up with the 1983 founding date on the commercial register rather than contradicting it. The site leans into being a known local fixture rather than a polished brand: one section is headed "Ein Dorforiginal mit Geschichte," a village original with history, under a direct quote from Bruno Troller: "Ein Fachgeschäft zeichnet sich nicht nur durch die qualitativ hochwertige Ausführung ihrer Arbeiten aus, am Anfang steht immer eine gute und personenbezogene Beratung. Beides ist mir wichtig." A specialty shop isn't only its finished work, he says, it starts with good, personal advice, and both matter to him.

How it's organized

The shop is closed Monday and open Tuesday, Wednesday and Friday from 9 to 12 and 13.30 to 18.00, with a longer Thursday that adds an evening slot the site calls "Abendverkauf" from 17.00 to 19.30, plus a Saturday morning from 9.00 to 12.30. Contact runs through a landline, 044 725 08 06, and a named email address, goldschmied@troller.ch, rather than an online booking calendar or contact form. The search.ch directory listing also shows the shop accepting cash, invoice, TWINT and Maestro cards, along with PostFinance's Postcard, so a newcomer without a Swiss credit history still has more than one way to pay. The site itself is a single WordPress page, with no separate about, pricing or English-language pages behind it, so there is no published price list, lead time or guarantee to report here; anyone who needs those terms will have to raise them in the first conversation rather than find them online.

How it compares

The practical case for Horgen over a central Zürich address is the train. Horgen's own station sits in the town centre next to the lake, on the S2 and S8 lines, and the fastest direct service to Zürich HB takes 18 minutes, one of roughly 94 trains a day covering the 14 kilometres between the two stations, so this reads as a commute rather than a day trip for anyone based in the city. A lake boat to Zürich's Bürkliplatz is also an option for a slower version of the same journey. Set against that convenience is language: the site is entirely in German, with no English version and no language switcher anywhere on it, so an expat reader should confirm by phone or email that a consultation can run in English before making the trip, since the site itself gives no signal either way.

Who it suits

This fits a buyer who already has a fairly clear idea of the stone they want, or who owns one already and needs a specialist to take it further, more than someone who wants to start from nothing with an open-ended design conversation. It also suits someone willing to travel a short way outside central Zürich and to make first contact in German, or at least confirm English works before booking time, given the shop runs on fixed hours rather than appointment software. It is a weaker fit for a same-week or last-minute request, since no lead times are published anywhere, and for a buyer who wants the whole process, from enquiry to collection, handled in English online.

The verdict

Troller earns its place in this category on specifics rather than general goldsmithing language: a diamond-first positioning stated on its own homepage, an in-house stone-cutting workshop rather than an outsourced one, a 1983 founding date on the Swiss commercial register, and matching five-star reviews on two separate directories describing a customer relationship of more than 20 years. The German-only site and the absence of any published pricing or lead time are real gaps for an international buyer used to shopping online first, but neither is a reason to skip a small workshop with this much evidence of long, hands-on, personally run work behind it. A phone call in German, or an email confirming English is possible, is a small price for access to a specialist who cuts his own stones an 18-minute train ride from the city.
