Are lab-grown diamonds real diamonds?

Yes. Lab-grown diamonds are real diamonds in every scientific sense — they have the same chemical composition (pure carbon), crystal structure, hardness, and optical properties as mined diamonds. The FTC confirmed in 2018 that lab-grown diamonds are genuine diamonds.

How much cheaper are lab-grown diamond engagement rings?

Lab-grown diamonds are typically 60–80% less expensive than equivalent natural diamonds. A 1ct F/VS1 lab-grown diamond engagement ring at MOH starts from approximately £1,200–£1,800, compared to £3,500–£5,500 for an equivalent natural diamond ring.

Are princess cut diamonds cheaper than round?

Yes. Princess cut diamonds are typically 20–30% less expensive than equivalent round brilliants because less rough stone is wasted during cutting. This makes them an excellent value choice for maximising size and sparkle within a budget.

Is £3,500 enough for a natural diamond engagement ring?

Yes — at MOH, £3,500 can secure a 0.7ct natural diamond solitaire engagement ring in 18K gold. If you prefer maximum carat size, a 1.5ct lab-grown diamond in platinum is also achievable at this budget.

Lab-grown diamonds are chemically, physically, and optically identical to mined diamonds. They have the same crystal structure, hardness (10 on the Mohs scale), refractive index, and thermal conductivity. The only difference is their origin — grown in a controlled laboratory environment in 6–10 weeks rather than formed over billions of years. Lab-grown diamonds are typically 60–80% less expensive than equivalent natural diamonds, allowing you to choose a larger, higher-quality stone within your budget.

The princess cut is a square or near-square brilliant-cut diamond that offers exceptional sparkle in a modern, geometric profile. It retains more rough diamond weight during cutting than a round brilliant, making it a strong value proposition without sacrificing fire or brilliance.
