Lab grown diamonds are just like mined diamonds. Grown in a laboratory using state of the art technology, they offer superb quality, beauty and value for money – whilst also being environmentally sustainable and ethical.
All our lab grown diamond jewellery is set in sustainably sourced metals.
All of our jewellery that features ethical and sustainable lab grown diamonds is also set in 100% recycled gold, platinum or silver. So that your entire jewellery piece is kind to the environment and local communities.
We always ask our customers to review the jewellery they buy from us. Here’s what one had to say about our lab grown diamond earrings.


ARE LAB GROWN DIAMONDS REAL DIAMONDS?
Yes, lab grown diamonds are chemically & optically identical to a natural diamond. They are grown in a laboratory using state of the art technology.
Exactly the same as mined diamonds, lab grown diamonds consist of carbon atoms in a lattice crystal structure.
DO LAB GROWN DIAMONDS LOOK THE SAME AS MINED DIAMONDS?
Yes. Lab grown diamonds have the same physical and chemical properties as mined diamonds so they look exactly the same.
They can only be told apart from their mined counterparts by using special laboratory equipment that can detect the very slight differences in crystal growth.


DO LAB GROWN DIAMONDS COME WITH A QUALITY CERTIFICATE?
Just like the mined diamonds we sell, our lab grown diamond solitaire pendants, earrings and rings at 0.25 carats and above come with a diamond certificate.
Simply click on the Product Specifications tab on our product pages to see any certificates included with your diamond.
WHAT ABOUT COLOURED LAB DIAMONDS?
Brilliant pink, blue and yellow lab grown diamonds are chemically & optically identical to a natural coloured diamond. They are grown, and get their natural colour, through a method that imitates Mother Nature.

ARE LAB GROWN DIAMONDS MORE AFFORDABLE?
Lab grown diamonds are hi-tech luxury goods. A fusion of art and technology, the process is exacting and expensive.
However, compared to the rarity of mined diamonds and the cost of finding and extraction, lab grown diamonds still offer a considerable saving.
ARE LAB GROWN DIAMONDS ETHICAL AND SUSTAINABLE?
Yes, lab grown diamonds are ethical and sustainable. While all the mined diamonds we sell are guaranteed conflict-free, additionally, our lab grown diamonds are the environmentally sustainable and ethical choice.
This is because they have not been mined from the ground and, therefore, their production protects the environment.


ARE LAB GROWN DIAMONDS FAKE?
No. Lab grown diamonds are formed using state-of-the-art technology to imitate mother nature and they are chemically & optically identical to a natural diamond.
Fake diamond alternatives, like cubic zirconia or moissanite, are manufactured from completely different raw materials, not true carbon crystals.
For example, cubic zirconia is made from zirconium dioxide and you only need to look at it with a naked eye to easily distinguish it from mined or lab grown diamonds.
ARE LAB GROWN DIAMONDS RIGHT FOR ME?
Whatever type of diamond you decide to buy, we promise you luxury with confidence.
The most important thing is that you pick a beautiful piece of jewellery that speaks to you personally.
Mined diamonds and lab grown diamonds are chemically & optically identical, so the decision is entirely yours – and now you have a world of choice.
