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.

Ursula DeNeefe
Fleur was amazing and designed the ring of my dreams. I have been complimented on it constantly!
Brittany Rae
I couldn’t be happier! My partner and I began the engagement ring process together at Larsen Jewellery with Emma, who helped bring my vision to life. She listened to my ideas, offered her expertise, and after I stepped back so the proposal could be a surprise, she guided my partner through the rest of the process. The result was everything I dreamed of and more!
Sam
I cannot recommend Larsen Jewellery enough. I came here for an engagement ring with a certain idea in mind and Celeste helped me create a piece that was exactly what I was envisioning. Throughout the whole process she was so enthusiastic and her attention to detail was amazing. Thanks to both Larsen and Celeste I was able to give my now fiancée a truly wonderful ring!
Robert K
I had a fantastic experience with Jacinta from Larsen in creating my partner's custom ring. I had spoken to many jewellers prior to Larsen and Jacinta was the first person who filled me with confidence and affirmation that they knew what they were doing. Communication was excellent and the turn around from start to finish was fantastic. Every step of the way was met with positivity and the attention to detail was second to none.

I cannot thank you guys enough for creating the perfect ring and memories for us
Jack Hure
I cannot say enough about the diligence, effort and transparency of Larsen Jewellers. They created the most beautiful engagement ring for my partner, and were amazing throughout the entire process. Whether you know very little, or a good deal about jewellery, they are wonderful and make you feel welcome, heard and confident. I could not recommend them any more, they are my most trusted jeweller now.

My partner and I did the make your own wedding band experience and it was amazing!!! Jason was a patient and fun teacher and the rings we made are beautiful.

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.
