Are lab-grown diamonds real diamonds?

Yes. Lab-grown diamonds are real diamonds — identical carbon crystal structure, hardness, refractive index and fire as mined diamonds. The only difference is origin: grown in a controlled environment instead of extracted from the earth.

Can you tell a lab-grown diamond apart from a natural one?

Not with the naked eye, a loupe, or even most jewellers’ tools. They are optically identical. Only specialised laboratory equipment can distinguish origin, which is noted on the certificate.

Do lab-grown diamonds hold their value?

Lab-grown diamonds cost far less up front, so the value is in what you get today — a much larger, higher-quality stone for the same budget. Montare also offers lifetime free upgrades, so your purchase keeps its full value toward a future piece.

Are lab-grown diamonds more ethical?

Lab-grown diamonds avoid the environmental disruption and supply-chain concerns of mining, and origin is fully traceable. For many couples that traceability is a key reason they choose lab-grown.

Lab-Grown vs Natural Diamonds

An honest comparison — from a brand that only sells lab-grown, and will tell you why.

The short version: a lab-grown diamond is a diamond. Same crystal, same physics, same sparkle. The differences that matter are origin, price, and traceability — not the stone on your hand.

The Montare standard (our floor, not our ceiling): every diamond is lab-grown, D–E colour, VVS1–VVS2 clarity, Triple Excellent cut with ideal table & depth, IGI certified, and 3 carat minimum. Made to order in Toronto.

Are they the same thing?

Chemically and optically, yes. Both are pure crystallised carbon graded to the same scale for cut, colour, clarity and carat. A lab-grown diamond is grown in weeks under the same heat and pressure that form a mined diamond over billions of years. Put them side by side and no one — not a jeweller, not a loupe — can tell which is which without lab equipment.

The real differences

	Lab-Grown	Natural (Mined)
Physical & optical properties	Identical	Identical
Certification (IGI/GIA)	Yes	Yes
Price for the same size & grade	A fraction	5–10× more
Origin traceability	Fully traceable	Often unclear
Environmental footprint	Lower, no mining	Higher, requires mining

What it means for your budget

Because lab-grown removes the scarcity premium, the same money buys a noticeably bigger, finer stone. It’s why Montare can hold a 3-carat, VVS, D/E, Triple Excellent floor on every ring — a standard that would be far out of reach with mined stones at the same price.

So which should you choose?

If you want the rarity story of a mined stone, that’s a personal choice. If you want the largest, cleanest, most brilliant diamond your budget allows — with traceable origin and a lower footprint — lab-grown wins decisively. That’s why we build every Montare ring with it.
