What are Cultured Diamonds?

Cultured diamonds are diamonds. They are also known as lab grown, created or man made. In this day and age, you can mine diamonds and you can grow diamonds. Both are just as hard, just as brilliant and just as everlasting because both are just diamonds. Real Diamonds.

Can my expert gemologist friend tell a mined diamond and a cultured diamond apart?  


Are cultured diamonds also graded? Can you get a certificate?

YES! Cultured Diamonds are graded in the same way as mined diamonds- by their colour, clarity, cut and carat. The GIA (Gemological Institute of America) and the IGI (International Gemological Institute), among other gemological institutes offer certificates for lab grown diamonds.

Are cultured diamonds more or less expensive?

Since there's no monopoly pricing and there's only 2 steps to obtain them (Grow & Cut), cultured diamonds are 30% to 50% less than mined ones.

How are diamonds grown?

We mimic the way diamonds grow under ground.

Theres 2 ways you can grow diamonds. One involves applying immense heat and pressure to carbon and the other involves applying heat and gases to a diamond slice.

Both processes create 100% diamonds; and watching both of these processes in real life is like magic, but real!

How are cultured diamonds more sustainable?

Cultured diamonds don't require huge amounts of land or wildlife displacement. Since they are not mined, and no huge holes on earth need to be dug up, they don't cause any under ground water pollution or release any chemicals into the ground. They are also guaranteed conflict-free every single time.

As renewables become more available, labs are also starting to switch their energy source to a higher percentage of green energy when growing diamonds. We work with a lab in the UK that can even grow diamonds with 100% renewable energy coming from wind and solar sources.


For more information on how growing diamonds with renewable energy vs mining them impacts our planet you can check out this study. The UK company we work with is also creating their own study, which we will update as soon as we have it. We have also spoken to an environmentalist PHD, Dr. Saleem H. Ali. Listen to our podcast with him on Diamond Disruptors or contact us and we'll be glad to send this over.

How pure are cultured diamonds?

Cultured diamonds are generally purer than mined diamonds since we can control the environment in which they grow. Only 2% of mined diamonds are as pure as cultured diamonds. This type of rare diamond is calledType 2a.

Do cultured diamonds shine as much as mined ones?

They shine exactly the same! It's all about the colour, cut, and clarity that you get!

Will my cultured diamonds last as long as my mined diamond?

Yeap! Just as long, in the exact same way.

What type of jewellery can you make with cultured diamonds?

The same type of jewellery made with mined diamonds can be made with cultured diamonds. This includes diamond rings, engagement rings, diamond necklaces, diamond stud earrings, diamond bracelets, etc.

People confess: Why I chose a cultured diamond.

"I am literally getting the same product, of a better quality and better sourced for a better price. Going back to mined would not make any sense!"

-Phillip from London

"I've read so much about the mining industry I just knew I couldn't keep partaking in that. I still love diamonds so this was the perfect choice for me."

-Leslie, Paris

Sustainability matters more than ever now. In a lot of industries you have to give up quality or pay much more to get access to a sustainable product. With diamonds it's quite the opposite. If this isn't enough reason to choose a cultured diamond over a mined one, I don't know what is.

More reasons to go cultured? L&B is here to help!

Diamond mining can be dirty.

Historically, the industry of diamond digging has been rife with conflict and has had an incalculably negative impact on the environment. Mined diamonds have been used to support war, conflict and human suffering.

It has long been time for a change in luxury jewellery… time for diamonds and stones to be sourced responsibly and have a more positive impact.


So how do we accomplish this?

Lark & Berry’s diamonds are NEVER mined. We use cultured diamonds and stones exclusively. NO conflict, guaranteed.


How can we say this?

Because we GROW all our diamonds!

Yes, you heard right—with the marvels of modern science, superior AND fairer-priced diamonds can now be created aboveground, in a lab, using innovative technology, completely eliminating the need to ever dig up and pollute another plot of land on Earth again.

It’s magic!

OK, well… not quite magic, but we like to think of our cultured stones as our own little miracles of engineering. Join our little merry band of diamond disruptors, and let’s shake up the luxury market—one piece of Lark & Berry jewellery at a time!
