What Are Lab Grown Diamonds?

There are two common ways Lab grown diamonds are created. Both are produced in a controlled laboratory environment. The first method is HPHT which stands for High Pressure, High Temperature. This technique simulates the extreme heat and pressure of the earth’s mantle. The other method is CVD which stands for Chemical Vapour Disposition. CVD diamonds are grown with less pressure and heat with the aid of carbon rich gasses. Both types of laboratory grown diamonds are chemically identical to mined diamonds. This means they share the same physical and optical properties. They exhibit the same fire and sparkle as mined diamonds and are graded using the same 4Cs as the major grading laboratories.

George Green
Larsen’s and the team were absolutely fantastic. I was looking for an engagement ring. The team were first class in breaking down different stones, sourcing and identifying the stone. And then from there it was smooth sailing with a concept design. Couldn’t have asked for a better experience.
Matthew Clarke
Emma and John at Larsen were great to deal with, they weren’t like other jewellers who just tried to talk me into the most expensive ring, they worked to get me a ring that was within my budget and looked exactly how I wanted it. Would highly recommend them, and we are now very happily engaged !
Reese S
Working with Larsen Jewellery to design a custom ring for my partner was a very easy and smooth process. Pricing was also reasonable.
Clarice G
We got our wedding bands from Larsen Jewellery. Both Alex and Jason were amazing. We decided on our wedding bands design with Alex just before he moved. Jason made our wedding bands and they were perfect. The whole process was very seamless and the experience has been wonderful.
George Brown
When looking for a wedding ring that would be beautiful and unique, I fell in love with the look of mokume gane style rings, with their unique wood grain pattern. I found Larsen, and Jason, and after a consultation where we discussed what I was after, Jason crafted the most beautiful ring I've seen, and far exceeded my expectations. A very professional service, with a high quality product, and a very fast delivery! (Seeing Jason handmade it from scratch!)

Would highly recommend Jason! Thank you!
Luke Ryan
Jason helped with the design and modification of my fiancé's novo wedding ring and she couldn't be more happier. Larsen have custom made her engagement and wedding rings and their service, reliability and prices have been amazing. Would recommend to anyone keen to go above and beyond. Thanks Larsen

Frequently Asked Questions

Still have questions? We’re happy to answer them! 

Are lab diamond engagement rings popular?

Lab grown diamond engagement rings are becoming increasingly popular. As awareness of ethical sourcing grows, many are drawn to lab diamond rings for sustainability reasons, and others love their affordability. If you're looking for the signature brilliance and sparkle in your ring, lab grown diamonds can sometimes be a great, budget-friendly alternative to traditional diamonds.

Do lab diamond engagement rings come with a certificate?

Yes, at Larsen Jewellery, our lab grown diamond engagement rings come with certificates, just like with natural diamonds. These documents detail the diamond's characteristics (including cut, colour, clarity, and carat weight), so that you can be confident in your purchase of a stunning and ethically sourced lab-grown diamond.

Why should I buy a lab diamond engagement ring?

Choosing a lab grown diamond engagement ring can offer ethical and environmental benefits. Lab-grown diamonds are conflict-free just like natural diamonds, but are often more affordable and can also be sourced with minimal environmental impact. They share the same physical and chemical properties as natural diamonds, and are subject to our same commitment to sustainability and responsible sourcing.

Do lab diamond engagement rings require special care and maintenance?

Lab grown diamond engagement rings require the same care as natural diamonds. Regular cleaning with mild soapy water and gentle brushing can help remove every day grime, as well as annual cleaning and checks by an expert to help them maintain their sparkle. Ask your jeweller for specific care advice to ensure your ring remains beautiful for a lifetime.

Are lab diamond engagement rings ethical and sustainable?

Yes, our lab grown diamond engagement rings are considered ethical and sustainable. We always endeavour to source stones produced with minimal environmental impact as a part of our commitment to being a carbon-neutral business.
