Diamond Bros & Co.

Last reviewed: September 24, 2026. Business status: Active.

Diamond Bros & Co. offers private engagement-ring appointments in Mississauga for couples comparing certified diamonds, custom settings and wedding jewellery. The official booking page presents a one-couple-at-a-time experience, with no payment details or obligation required to reserve an appointment. For couples searching for Mississauga engagement rings, the company provides a starting point for viewing stones in person, discussing designs and receiving a written quote.

The business lists three GTA appointment locations, including its Port Credit consultation suite at 76 Lakeshore Rd E and its Airport Road showroom and atelier. This profile was last reviewed on September 24, 2026, using the supplied official booking page. Couples should confirm current showroom details, appointment times, design timelines and the terms of any purchase directly with Diamond Bros & Co.

Services and specialization

The official page focuses on engagement rings, diamonds, custom rings and related wedding jewellery. Couples can view loose stones with their certificates, discuss settings and review examples such as solitaires, halo designs, oval-cut rings, bridal sets, baguette bands and eternity bands. The page also describes necklaces, bracelets, earrings and men's pieces for couples considering jewellery beyond the engagement ring.

Diamond Bros & Co. states that settings are designed and finished at its own bench at the Airport Road atelier. The company also says that prongs are set by hand and that custom pieces are generally made in a few weeks after design approval. A specific delivery date is not guaranteed on the page, so couples with a wedding deadline should discuss timing before approving a design.

• Engagement rings and loose certified diamonds
• Custom rings and settings
• Bridal sets, wedding bands and matching pieces
• Necklaces, bracelets, earrings and men's jewellery
• Cleaning, checks, tightening and resizing support described as part of lifetime care

Service area and who it may suit

Diamond Bros & Co. lists three GTA locations: Airport & Derry at 7160 Airport Rd in Mississauga, Port Credit at 76 Lakeshore Rd E in Mississauga, and a Mayfield consultation suite in Brampton. The supplied company page is therefore most relevant to couples in Mississauga, Brampton and the wider GTA who can attend an appointment in person.

The appointment format may suit couples who want to compare stones at a showroom, ask questions across a private consultation and take a written quote away before deciding. The official page says that no purchase is required on the day. Couples who need remote consultations, a particular diamond specification or a location outside the listed GTA showrooms should confirm whether those options are available.

• Mississauga locations include Port Credit and Airport Road
• A Brampton consultation suite is also listed
• Appointments are described as private and one couple at a time
• The official page says appointments have no cost and no obligation

Confirmed strengths and practical limitations

Documented features include GIA or IGI certification for the diamonds described on the official page, certificates shown beside loose stones, custom work completed at the company's own bench and a stated lifetime warranty and care programme. The page describes that care as including cleaning, inspections, prong checks, tightening and resizing support for as long as the customer owns the piece.

The available evidence is limited to the company's own booking page. It does not provide a public price list, a complete explanation of warranty exclusions, or detailed product-by-product specifications. The page also refers to limited appointment slots, but it does not establish availability for a particular date. These are practical points to confirm rather than negative findings.

• Certified-stone information is published by the company
• Custom finishing at the company's own bench is described
• Lifetime care and warranty support is stated
• Public prices, warranty exclusions and date-specific availability are not provided in the supplied evidence

Pricing

Prices are not published on the supplied official page. The company states that every price is quoted in writing and describes the appointment as free, with no payment details, deposit or obligation required to book. Couples can therefore use the consultation to discuss a stone and setting, then review the written breakdown before making a purchase decision.

The page does not establish a standard starting price, a package price, a price range or the final cost of custom work. Ask for the complete written quote, including the stone, setting, labour, applicable taxes and any resizing or care terms that may affect the purchase.

• Prices are not published
• The appointment itself is described as having no cost
• The company says every price is quoted in writing
• Confirm taxes, custom-work charges and warranty terms in the written quote

Contact and booking

Appointments can be requested through the official booking page or by calling (647) 860-2767. The booking form asks for contact details and allows couples to select a preferred showroom. The listed Port Credit location is 76 Lakeshore Rd E, Mississauga, ON L5G 1E1. The official page lists Tuesday-to-Sunday hours of 11:30 a.m. to 7 p.m. and says the locations are closed Monday.

The booking page says that couples receive an instant confirmation and a text reminder the day before. Because hours and appointment availability can change, confirm the current details when booking, particularly during the wedding season.

What couples should confirm

Before attending, couples should identify the type of ring or jewellery they want to compare and share any important wedding date. Ask which stones and settings will be available at the appointment, whether a requested design can be custom-made, and how long production is expected to take from approval.

It is also useful to request the full written price breakdown and ask what is included in the lifetime warranty and care programme. Confirm resizing conditions, inspection and cleaning arrangements, certification details, return or alteration terms and the expected completion date before placing an order. These questions are especially important because the supplied evidence does not publish prices or complete purchase terms.

• Which stones and settings are available for the appointment?
• What is the complete written price, including taxes and custom work?
• What does the lifetime warranty cover and exclude?
• What is the expected production and delivery timeline?
• What are the resizing, return and alteration terms?

A practical starting point for GTA ring planning

Diamond Bros & Co. presents a private, appointment-based way to explore engagement rings, bridal sets and custom wedding jewellery in Mississauga and Brampton. Its official page documents certified-stone viewing, in-house bench finishing, written quotes and ongoing care support. The strongest next step for an interested couple is to book a consultation, explain the budget and wedding timeline, and leave with written details to compare before committing.

As with any custom jewellery purchase, the profile should be treated as a starting point rather than a substitute for the company's current quote and terms. Confirm the showroom, availability, specifications, pricing and completion date directly with Diamond Bros & Co.
