St-Onge Jewellery

Last reviewed: August 12, 2026. Business status: Active.

Last reviewed: August 12, 2026. St-Onge Jeweller is a Montreal jewellery business with an official English-language site that specifically presents engagement rings, wedding bands for women and men, and other fine jewellery. The current site identifies its Montréal location as both a boutique and workshop, providing clear first-party confirmation of the business identity, wedding focus, address and telephone number.

For couples searching for Montreal engagement rings, the useful distinction here is the maker-led focus: the company says its engagement rings are made in Quebec in its Montréal atelier and describes options for personalized creation. Its online catalogue also provides a practical starting point for comparing listed designs and prices before a consultation. This profile reports only information published on the official St-Onge domain; it does not treat the former listing text as evidence.

Services and specialization

St-Onge Jeweller’s wedding offering includes engagement rings and wedding bands for women and men. Its official wedding page organizes engagement rings by style, including solitaire, halo, trinity setting and diamond-band styles, and by diamond shape, including round, oval, cushion and marquise. This makes the business relevant to couples who want to begin with a defined ring category rather than a broad, unspecified jewellery search.

The official engagement-ring collection also documents a personalized creation service for someone who has a particular idea or does not find the desired design in the catalogue. The business additionally lists jewellery repair among its services. The available official material supports wedding rings, custom discussion and repair; it does not publish a wedding-package format, proposal planning service or a guaranteed production timeline for custom work.

• Engagement rings
• Wedding bands for women and men
• Personalized creation
• Jewellery repair
• Fine jewellery, including rings, earrings, bracelets, necklaces and pendants

Service area and who it may suit

The confirmed address is in downtown Montréal, where St-Onge identifies its location as a boutique and workshop. Its official boutiques page also identifies Bijouterie Pénélope in Québec City as an official retailer. That is evidence of two published points of purchase, not evidence of a broader in-person service area or of travel to clients’ locations.

This profile may suit couples who want to view engagement-ring and wedding-band designs in Montréal, who prefer a workshop-based source for their ring, or who are comparing certified Canadian and lab-grown diamond options. It may also be useful for shoppers considering gold, palladium white gold or platinum. Couples outside Montréal should ask directly about remote consultation, shipping, resizing, delivery timing and after-sales arrangements before relying on those options.

• Confirmed Montréal boutique and workshop
• Official retailer listed in Québec City
• No broader service radius is published on the reviewed official pages

Confirmed strengths and practical limitations

A documented feature is that St-Onge says its engagement rings are made in its Montréal atelier and that its creations are drawn, produced, set and polished there. The official collection states that engagement rings are available in 14k or 18k metals, while the same page says white gold with palladium and platinum can be selected for engagement-ring creation. It also lists certified Canadian diamonds and lab-grown diamonds as options.

The company states that its creations carry a lifetime guarantee. Its FAQ narrows that claim: the guarantee applies to manufacturing defects and excludes damage associated with non-recommended use, self-repair, alteration or inadequate maintenance. This is a useful published feature, but couples should read the current warranty terms before purchase because the profile cannot determine how a particular ring, alteration, stone or future repair would be handled.

• Montréal workshop production is documented
• Certified Canadian and lab-grown diamond options are documented
• Lifetime guarantee is published, with stated exclusions
• Custom timing, stone specifications and final warranty applicability require direct confirmation

Pricing

Current pricing is explicitly published for many online engagement-ring designs. At the time reviewed, examples on the official collection included the Cassie engagement ring from $1,495 CAD, the Audrey from $1,935 CAD, the Florence from $2,095 CAD, the Sophia from $2,775 CAD and the Toi et Moi engagement ring from $5,255 CAD. Some listed designs carry fixed displayed prices, such as the Leticia at $11,800 CAD and the Esmeralda at $12,895 CAD.

These are online starting or listed prices for named designs, not a complete wedding-ring budget or a quote for a customized piece. The official pages reviewed do not publish one universal price for bespoke work, diamond upgrades, matching bands, resizing, taxes, shipping or repairs. Couples should request a written estimate for the specific metal, centre stone, setting and any matching band before deciding.

• Published online engagement-ring prices begin at $1,495 CAD for a listed design
• Several listings use “from” pricing
• Custom-work pricing is not published as a single standard amount

Contact and booking

The official boutiques page lists St-Onge Jeweller at 620 Cathcart, ROOM 400, Montreal, QC H3B 1M1, with telephone number 514-871-1676. Published hours are Monday to Friday from 10:00 a.m. to 5:00 p.m., Saturday from 10:30 a.m. to 3:00 p.m., and Sunday closed. The page also notes a summer-vacation closure from July 20 to August 1, 2026, which has already passed as of this review date; hours and special closures can change, so verify them directly before visiting.

The official site invites visitors to contact the team or book an appointment, and its contact page includes a web form. For a ring consultation, sharing a target style, preferred metal, approximate budget range and any deadline can help the business advise on available choices. The site does not state that appointments are mandatory, so that practical point should be confirmed when contacting the shop.

• Phone: 514-871-1676
• Official website contact form is available
• Confirm current hours, appointment expectations and turnaround before visiting

What couples should confirm

Ask whether the exact catalogue ring can be viewed in Montréal, whether a matching band is available, and which elements can be customized. For diamond-led designs, confirm the stone’s type, certification and the specific characteristics included in the quote. The official site explains that both Canadian and lab-grown diamonds may be available, but it does not make every stone’s specification visible on this profile.

Also confirm the completed price in Canadian dollars, including taxes and any changes resulting from metal, stone or setting selections. If a ring is needed for a particular proposal or wedding date, ask for the current production and sizing schedule in writing. Finally, ask how the published lifetime guarantee applies to the chosen design and what routine care or future resizing entails.

• Availability of the chosen design and matching band
• Custom-work scope and written timeline
• Stone details and certification for the quoted ring
• Final price, taxes and any alteration costs
• Warranty coverage and maintenance requirements

Profile scope and local-search guidance

St-Onge Jeweller is a confirmed active profile because the official domain matches the distinctive St-Onge name and directly documents relevant wedding services: engagement rings and wedding bands. The same official domain provides the Montréal workshop context and the current contact details used above.

Use the brand name when looking specifically for this business, and use the primary local query when comparing ring options in Montréal. For broader planning resources, Canada Wedding Guide’s directory and wedding-shop hubs can help couples continue their search without conflating this individual jeweller profile with an all-vendor category page.
