Lab-Grown Engagement Rings in Toronto

Made here, to a standard the industry won’t promise.

Montare Diamonds is a Toronto-based maker of lab-grown engagement rings and wedding bands. We’re not a showroom reselling someone else’s inventory: every ring is designed with you first, cast from its approved CAD model and hand-finished in the Greater Toronto Area, backed by more than 30 years of family diamond-jewellery craft. There is no retail floor and no sales counter — just one-on-one consultations by phone or email, and a ring made to order around a diamond sourced to your design.

The Montare standard (our floor, not our ceiling): every centre diamond is D–E colour, VVS1–VVS2 clarity, Triple Excellent cut with ideal table & depth, IGI certified, and 3 carat minimum. Lab-grown as standard; mined diamonds by special commission, held to the same floor. Made to order in Toronto.

Why buy lab-grown in Toronto

Buying direct from a Toronto maker means no retail markup stack and no compromise on the stone. Every Montare centre diamond meets the same floor — D/E colour, VVS clarity, Triple Excellent cut, 3 carat minimum, IGI certified — so the only thing you’re choosing is the design you love.

A lab-grown diamond is a real diamond: chemically, physically and optically identical to a mined one, and graded by the same laboratories. The difference is origin, and origin is what changes the price. A three-carat, D–E, VVS, Triple Excellent stone that would be out of reach as a mined diamond becomes attainable when it is grown — without giving up size, colour or clarity. If you would still prefer a mined diamond, we source one by special commission, held to exactly the same floor. Our comparison of lab-grown and natural diamonds sets out the differences honestly.

How it works

  • Design — build your ring online, or start with a consultation by phone or email.
  • Confirm — Vish reviews the design with you one-on-one: proportions, profile, metal and sizing. The design is settled first; the diamond is then sourced to it.
  • Crafted — cast, hand-set and hand-finished in our Toronto workshop and delivered in 2–4 weeks, fully insured.

Serving Toronto and the GTA

We work with couples across Toronto and the Greater Toronto Area, including Scarborough, Mississauga, Brampton, Vaughan, Markham, Richmond Hill, Oakville, Burlington, Milton, Halton Hills and Caledon, as well as Guelph and Orangeville. Because there is no showroom to visit, distance makes no difference to the process: consultations happen by phone or email, and the finished ring is delivered to your door free, fully insured and signature-required.

Buying in Ontario: HST and delivery

Engagement rings bought in Ontario carry 13% HST, calculated at checkout before you pay. Delivery is included on every ring, fully insured from our workshop to your hands. If the ring needs to be at a particular place on a particular date, tell us at the consultation — made-to-order work is planned backwards from the day that matters, not squeezed in around it.

Where to propose in Toronto

Once the ring is ordered, the next question is where to ask. Our guide to the best places to propose in Toronto covers nine spots across the city, with the practical details that make the moment go to plan. If you are still working out timing, see how far in advance to buy the engagement ring.

What “wholesale” really means in Toronto

Plenty of Toronto jewellers advertise wholesale engagement rings. The word itself guarantees very little, and the certificate usually tells you more than the sign on the door. Our guide to wholesale engagement rings in Toronto explains what the term does and does not mean, and what to check before you buy.

Not in Toronto?

The same standard and the same made-to-order process reach every province. Our city guides cover buying a lab-grown engagement ring in Ottawa, Montreal, Quebec, Winnipeg, Calgary and Vancouver, and our guide to lab-grown diamond engagement rings in Canada covers the rest.

Five things to check before you buy, and how we answer them

  1. The grading report. Every engagement-ring centre diamond comes with its IGI report. Before it is set, you receive the certificate and a 360° video and approve the exact stone.
  2. The cut. Triple Excellent cut, polish and symmetry, with table and depth held to ideal ranges for the shape. Cushions and radiants are elongated only.
  3. The setting. Every ring is cast from the CAD model you approve, then finished and set by hand at the bench in our Toronto workshop.
  4. Aftercare in writing. A lifetime warranty on manufacturing defects such as prong tightening and stone resetting, one complimentary resize within the first year, and Lifetime Setting Upgrades.
  5. Returns and price. Standard pieces have 60-day returns; bespoke pieces are not returnable once production begins. Every ring is priced as the setting plus the centre diamond, so you can see what each part costs.

The Montare promise

Beyond the ring: a $500 personalisation credit, lifetime setting upgrades — trade your setting up in value whenever your taste changes, and keep the diamond you started with — and a diamond standard we won’t lower. Explore the engagement collection or design your own.
