Sustainable Lab Grown Diamonds

Not all lab-grown diamonds are created equally. It is true that lab-grown diamonds may not have the same environmental impact on the earth as mined diamonds. However, they do consume a considerable amount of energy during the production process.

As an ethically-minded business, we choose to source sustainable and ethical lab-grown diamonds.  We have selected companies that align with our core values. We consistently research our suppliers to ensure our high ethical standards are upheld along our supply chain.

Being a carbon-neutral business, we partner with laboratories at the forefront of sustainability.  Our preferred suppliers advocate ethical, sustainable, and environmentally responsible practices. These suppliers uphold the five pillars of sustainability under the SCS 007 jewellery standard. They use clean, renewable energy as per the ‘SCS Global’ sustainability audit process. Hydro and solar power is used to grow their diamonds, honouring our commitment to our certified carbon neutrality status.

We make it our mission to be completely transparent, genuine, and unbiased in all our business practices. This allows us to offer you lab-grown diamonds of the highest ethical integrity.

Laura Ovens
We originally got our wedding rings with Larsen 10 years ago, and had such a good experience went back for a custom piece. Rachel and the team were incredible every step of the way and made the thoughts in my head come to life in a piece that I will cherish forever. Would definitely recommend!

We stumbled upon Larsen Jewellery by chance while shopping for our wedding rings, as I was struggling to find a design that complemented my custom engagement ring. Alex was super kind and took us in even though we didn’t have an appointment, and right then and there, he sketched my dream wedding ring. I knew instantly it was the one!

Alex’s experience and incredible attention to detail made the whole process so smooth and enjoyable. He truly brought my vision to life. I can’t recommend Larsen enough, and I’m already looking forward to getting another custom piece made in the future!
Yasmeen F
For engagement rings, this is the BEST place! We visited a few shops around (including one very very nearby), and Larsen was hands down the best. We had our appointment with Ben, who was an amazing help throughout the selection process. The point of difference for us was that Ben was the actual jewelry maker, which meant we could lean on him for his expertise and you could tell he genuinely cared. Out of all the shops we went to, Larsen sourced the best looking stones and made the process fun. The showroom is beautiful too. Cannot recommend enough!
Chris Penfold
Soukata was amazing to work with. She was so patient throughout the whole process, helping me design a Toi et Moi ring that my fiancée absolutely loves. I wasn’t always sure what I wanted, but she guided me with thoughtful suggestions and never rushed anything. The final ring turned out beautifully—elegant, personal, and exactly what I was hoping for. Highly recommend Larsen to others!
Justin Le
Amazing ring for our special moment! Great service as the team was doing there best to help me to get the ring I wanted in such a tight timeline.
Brittany Reeves
Soukata did an amazing job helping to design my engagement ring and our wedding rings. We absolutely loved our experience at Larsen - nothing was too much trouble and all their jewellery is just beautiful.
