So… What Exactly Are Lab Grown Diamonds?

Let’s clear this up first: lab grown diamonds are real diamonds.
They’re not simulants like cubic zirconia or moissanite. Lab diamonds are chemically, optically, and physically identical to those mined from the earth. The only difference is they are created in a high-tech lab using methods like CVD (Chemical Vapour Deposition) or HPHT (High Pressure High Temperature).

... And yes, they sparkle just as much.

Why UK Shoppers Are Switching to Lab Diamonds

Better Value for Money
Let’s be honest — weddings and proposals can get expensive fast. The good news? Lab grown diamonds cost around 30–40% less than mined ones of the same size and quality. That means a bigger, brighter stone for your budget.

Ethical & Conflict-Free
There’s growing concern about the ethics of mined diamonds. Lab grown stones are conflict-free by nature, with no links to environmental harm or human rights abuses.

Crafted in Britain
Our engagement rings are made right here in the UK. From design to finish, we work with skilled British jewellers to create heirloom-quality pieces you’ll love for a lifetime.

Certified Quality
Every feature lab grown diamond we offer is independently graded by reputable laboratories such as the International Gemological Institute (IGI) or Gemological Institute of America (GIA), ensuring you receive a high-quality, certified diamond. (smaller accent diamonds are not certified)

Popular Lab Grown Diamond Engagement Ring Styles

Not sure where to start? Here are some customer favourites:

  • Solitaire: Clean, timeless, and all about the stone.
  • Halo: A sparkling border of diamonds enhances the size and brilliance of your centre stone.
  • Trilogy: Symbolising the past, present, and future, this design features three beautiful stones.
  • Hidden Halo: Subtle details for extra sparkle and elegance.

What to Look for When Buying a Lab Diamond

When buying a lab grown diamond with an IGI certificate, the same 4C's apply as they do with natural diamonds: cut, colour, clarity, and carat weight. Here’s a quick guide:

  • Cut: Impacts sparkle the most. Choose “Excellent” or “Ideal” cuts.
  • Colour: For a white diamond, opt for colour grades D–F (collection colours).
  • Clarity: VS1 or higher gives you a clean look, often without visible inclusions.
  • Carat Weight: Lab diamonds allow you to go bigger for less.

The IGI has also introduced Light Performance Analysis, a scientifically grounded assessment of a diamond’s sparkle. It measures brightness, fire, and contrast, to complement the traditional 4C's.

Starting from the later part of 2025, when buying a lab grown diamond with a GIA certificate, it will no longer state the 4C's. Instead, diamonds will be categorised into two simplified tiers “premium” or “standard” based on combined evaluations of colour, clarity, and finish. Diamonds failing to meet minimum quality thresholds may receive no designation at all.

Lab Diamond FAQ's

Are lab grown diamonds real?

Yes. Lab grown diamonds are 100% real diamonds, with the same physical and chemical properties as mined ones. Learn more on lab grown diamonds with IGI.

Do lab diamonds last as long as mined diamonds?

Absolutely. They are just as durable and will last forever, making them perfect for engagement rings.

Can I insure a lab grown diamond?

Yes, they are insurable just like mined diamonds. We recommend using a provider that understands the current market for lab grown diamonds.

Will people know it’s lab grown?

Only if you tell them. Even jewellers need specialised equipment to tell the difference.
