The Montare Diamond Standard
What every Montare diamond is guaranteed to be — and why we made it the floor.
Every Montare diamond is lab-grown, IGI-certified, and held to one standard regardless of price, shape or setting: D–E colour, VVS1–VVS2 clarity, Triple Excellent cut with ideal proportions for its shape, and a 3-carat minimum centre stone. There is no lower tier to opt into and no upgrade to pay for — we removed the compromises, so there is no wrong choice to make.
The standard at a glance
Most jewellers quote a “starting” quality and let cost pull you down from there. Montare starts where most stop. Here is the floor most retailers offer next to the bar every Montare stone already meets:
| Spec | Common retail floor | The Montare standard |
|---|---|---|
| Origin | Mined or unspecified | Lab-grown, every stone |
| Colour | G–J (near-colourless) | D–E (colourless) |
| Clarity | SI–VS | VVS1–VVS2 |
| Cut | Very Good+ | Triple Excellent + ideal table & depth |
| Carat | 1ct+ | 3ct minimum |
| Certification | Varies / sometimes none | IGI on every stone |
Cut & proportions, calibrated to each shape
Cut is what makes a diamond return light, so it is the spec we hold most precisely. Every Montare diamond is Triple Excellent — top grade for cut, polish and symmetry — and cut to the ideal table, depth and length-to-width range for its shape:
| Shape | Ideal table | Ideal depth | Ideal L : W |
|---|---|---|---|
| Round | 54–57% | 59–62.5% | 1.00 |
| Oval | 54–58% | 58–62% | 1.35–1.50 |
| Cushion | 58–62% | 61–67% | 1.00–1.10 |
| Emerald | 62–66% | 61–67% | 1.30–1.50 |
| Radiant | 62–66% | 61–67% | 1.05–1.35 |
| Pear | 54–58% | 58–62% | 1.45–1.70 |
| Marquise | 54–58% | 58–62% | 1.85–2.10 |

Certified, and approved by you before it is set
Every stone is IGI-certified (International Gemological Institute) to the proportions above. Before your diamond is set, you receive its certificate and a 360° video and approve the exact stone — you are never asked to take our word for it. Lab-grown vs natural explains why a lab diamond is chemically and optically identical to a mined one.
Transparent diamond pricing
The stone is priced separately from the setting, by the carat, at a published rate — so you can see exactly what you are paying for. All prices in CAD:
| Clarity & colour | Price per carat (CAD) |

The ring setting is priced separately. For worked examples by shape and size, see how much a 3-carat lab-grown diamond costs.
Made to order in Toronto
Each ring is built to order over three to four weeks and shipped across Canada. Choosing a Canadian maker also avoids the cross-border duties that imported rings can carry. More on lab-grown rings in Canada and in Toronto.

What is the Montare diamond standard?
Every Montare diamond is lab-grown and IGI-certified, with D–E colour, VVS1–VVS2 clarity, a Triple Excellent cut with ideal proportions for its shape, and a 3-carat minimum centre stone. It is the same standard on every ring, at every price — the floor, not an upgrade.
Are Montare diamonds lab-grown or natural?
Every Montare diamond is lab-grown. A lab-grown diamond is chemically, physically and optically identical to a mined diamond; it is a real diamond, simply created above ground, which is what makes colourless VVS quality affordable.
What colour and clarity are Montare diamonds?
D–E colour (the colourless range) and VVS1–VVS2 clarity — inclusions very difficult to see even under 10x magnification. Most retailers default to G–J colour and SI–VS clarity; Montare sets D–E and VVS as the floor.
Are Montare diamonds certified?
Yes. Every stone is independently certified by IGI (the International Gemological Institute) to its stated 4Cs and proportions. You receive the certificate and a 360° video and approve the exact diamond before it is set.
What is the minimum carat size at Montare?
Three carats. Every Montare engagement ring centres a stone of at least 3 carats — a presence that lab-grown pricing finally makes attainable.
How much does a Montare diamond cost?
The diamond is priced separately from the setting, by the carat, in CAD: VVS2 E is $750/ct, VVS1 E is $1,100/ct, VVS2 D is $1,260/ct and VVS1 D is $1,575/ct. The ring setting is priced separately.
Where are Montare diamonds made?
Montare rings are made to order in Toronto, Canada over three to four weeks and shipped Canada-wide. Buying from a Canadian maker also avoids the cross-border duties that imported rings can carry.
