Question 1

Are lab-grown diamonds real diamonds?

Accepted Answer

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.

Question 2

How much cheaper are lab-grown diamond engagement rings?

Accepted Answer

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.

Question 3

Are princess cut diamonds cheaper than round?

Accepted Answer

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.

Question 4

Is platinum worth the extra cost for an engagement ring?

Accepted Answer

Platinum is typically 20–40% more expensive than white gold, but it offers superior durability, purity, and zero maintenance over a lifetime. It never needs re-plating and is naturally hypoallergenic. For a piece you will wear every day for decades, many find the investment worthwhile.

Question 5

What shapes work best in a three stone engagement ring?

Accepted Answer

Round and oval centre stones are the most popular for three stone rings. The side stones can match the centre or use complementary shapes — pear or trapezoid side stones flanking a round or oval centre create a beautiful, balanced design.

Question 6

Should I choose lab-grown or natural diamond for under £3,000?

Accepted Answer

Under £3,000, you can choose a larger lab-grown diamond (1ct–1.5ct) or a smaller but geologically rare natural diamond (0.5ct–0.7ct). Lab-grown maximises size and sparkle; natural offers rarity and tradition. Both are excellent choices.
