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.

It was a pleasure to have Alex as our jeweller and we knew from the first consult that Larsen jewellery is the place to design our engagement ring. Alex was knowledgeable and honest, the ring design process was easy and he explained every step of the way. We couldn't be more happy with the final product. My fiancé has received many positive comments and she is extremely happy with the ring!

I recently purchased an engagement ring from Georgia and the team, and I couldn't be happier with the experience. From start to finish, Georgia was incredibly helpful, knowledgeable, and patient throughout the entire process. She took the time to answer all my questions, helped me find the perfect ring, and made what could have been a stressful decision feel easy and enjoyable. The quality of the ring is absolutely outstanding, and my fiancée was blown away when I proposed. The attention to detail, communication, and genuine care shown by the team made the whole experience memorable. I highly recommend Georgia and the team to anyone looking for exceptional service and beautiful jewellery. Thank you again for helping make such an important moment in our lives so special.

She said yes! We couldn't be more grateful to Jacinta and the team at Larsen. We booked a last-minute appointment on a whim, and it turned out to be the only jeweler we needed to visit. My partner dreamed of designing her own engagement ring, and Jacinta was an absolute angel in helping us bring that to life. As total novices, her deep knowledge of the design process, metals, and lab-grown diamonds gave us so much confidence. She guided us with such warmth and encouragement that we knew exactly what we wanted from day one. The finished ring is absolutely stunning, and my fiancée gets endless compliments on the gorgeous design. Thank you so much to the entire team. If you are new to the world of jewelry or just looking for incredibly skilled people who truly care, I highly recommend 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.

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.
