Global Diamond Montreal is a downtown jewellery retailer and e-commerce store for couples researching Montreal custom engagement rings, wedding bands and diamond jewellery. Its official website presents engagement-ring settings, wedding-band collections and a design-your-own-ring route, with appointments offered online, virtually or in store.

The business says it has worked in diamond jewellery manufacturing and retail for more than 40 years, with its Montreal operation established in 1992. Couples can use a consultation to discuss a setting and centre stone, review available options and clarify the specifications that matter before buying.

Services and specialization

Global Diamond Montreal’s wedding-focused inventory includes engagement rings, wedding bands, eternity rings and semi-eternity rings. The official store separates engagement rings into solitaire and halo categories. Its wedding selection includes gold bands, diamond-set styles and men’s wedding bands.

Custom work is a confirmed part of the offer. The site invites customers to design an engagement ring by starting with either a setting or a centre stone, while its About page describes the business as a custom jewellery designer. This may be useful for couples who have a reference style, want to choose the stone separately from the mounting, or are trying to coordinate an engagement ring with a wedding band.

The site also sells jewellery outside the wedding category, including earrings, necklaces, bracelets and men’s jewellery. Those products may be relevant for gifts, but the reviewed official pages do not give a detailed, item-by-item description of what a custom bridal commission includes.

Service area and who it may suit

The confirmed showroom is in downtown Montreal at 620 Rue Cathcart, Suite 206, on the second floor. The official site says the showroom serves customers in Montreal, the Greater Toronto Area and beyond, but it does not publish a complete service-area list or delivery boundary.

This may suit Montreal couples who want an in-person ring consultation, as well as clients elsewhere who are comfortable starting virtually. It may also suit shoppers comparing natural and lab-grown diamond options, or people looking for both an engagement ring and a wedding band. Out-of-town clients should confirm the practical arrangements for their specific order before purchase.

Confirmed strengths and practical limitations

A documented feature is the business’s diamond-jewellery history. Its About page says the business began as a diamond-polishing manufacturer in 1982 and established its Montreal base in 1992. The homepage also describes more than 40 years of craftsmanship and highlights custom designs.

Choice is another confirmed feature. The site says it carries GIA-certified earth-grown diamonds and IGI-certified lab-grown diamonds. Its online wedding inventory shows a variety of metals, widths, diamond weights and setting types.

There are practical evidence limits. The reviewed pages do not set out a complete bespoke-design workflow or a firm production schedule for every custom ring. The FAQ contains policy information, but couples should request the terms that apply to their exact design, including alterations, returns and warranty coverage, in writing.

Pricing

Current pricing is explicitly published for many ready-to-buy items on the official online store, in Canadian dollars. At the time reviewed, examples in the Wedding Bands collection included a high-polish yellow-gold 3 mm wedding band at CAD 937, a men’s brushed-gold 4 mm wedding band at CAD 1,125 and a double-milgrain 6 mm wedding band at CAD 1,375. Other listed bands and diamond styles were priced higher depending on the design and stones.

No fixed starting price or published price range was found for a custom engagement-ring commission. The final cost will depend on the selected setting, metal, centre stone and any additional diamonds. Online prices can change and should not be treated as a quotation for a bespoke ring.

What couples should confirm

Before booking, confirm whether the appointment will be virtual or in person and whether a particular ring can be viewed at the showroom. For a custom engagement ring, ask about the design-approval process, deposit and payment schedule, expected production timeline and whether changes can be made after approval.

For any diamond, confirm whether it is natural or lab-grown, the issuing laboratory report, the stone’s full specifications and whether the quoted price includes the setting. For wedding bands, ask about sizing, engraving if wanted, matching-band availability and the policy for alterations or returns.

The FAQ says custom orders cannot be returned or exchanged, while custom-made rings are included in a 90-day resizing warranty. It also states that shipping costs for resizing are the customer’s responsibility. Confirm the exact terms, exclusions and costs applicable to the proposed ring.

Background and wedding-planning context

The official About page refers to Doctor Diamond Jewelry, while the storefront uses the Global Diamond Montreal name and displays matching Montreal contact information. The business describes itself as a diamond-jewellery and e-commerce store, with wedding-related ring categories, custom design and an appointment route from its Montreal showroom.

This profile is a research starting point rather than a product-specific quote or contract. Availability, promotions, prices and appointment times can change, so confirm them directly with the business before making a purchase decision. Last reviewed: August 11, 2026.
