Question 1

How much does a 1 carat lab-grown diamond cost in the UK?

Accepted Answer

A 1 carat IGI certified lab-grown diamond at Diamond Labs typically costs between £180 and £500 depending on colour, clarity, and cut grade. Prices are transparent with no hidden markups.

Question 2

Are lab-grown diamonds real diamonds?

Accepted Answer

Yes. Lab-grown diamonds are real diamonds with the same chemical composition (pure carbon), crystal structure, and optical properties as mined diamonds. Even professional gemologists need specialist equipment to tell them apart.

Question 3

What is the difference between IGI and GIA diamond certificates?

Accepted Answer

Both IGI and GIA are internationally respected grading laboratories. IGI is the world's largest independent diamond grading lab and is widely used for lab-grown diamonds. All diamonds at Diamond Labs are IGI certified.

Question 4

Do lab-grown diamonds hold their value?

Accepted Answer

Like mined diamonds, lab-grown diamonds do lose value after purchase. However, because lab-grown diamonds cost significantly less upfront, the absolute financial loss is much smaller. They are best viewed as a purchase for joy rather than investment.

Question 5

How long does delivery take for lab-grown diamonds in the UK?

Accepted Answer

Diamond Labs offers free UK delivery. Diamonds are shipped from our UK inventory and typically arrive within 3–5 working days, fully insured.
