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.

We had a lovely experience at Larsen. Lulu helped us land on the perfect design with both expertise and patience, producing a bespoke ring that is uniquely stunning. My new fiancée and I could not be happier - she is absolutely obsessed with the gorgeous ring.
Lulu was also highly professional throughout the process, keeping details such as timelines and cost discreet so that I could still surprise my partner once the ring was ready and the moment was right.
I would highly recommend Larsen for the quality of both service and jewellery, and have been delighted by the whole process. Thank you!

We had a great experience with Larsen Jewellery. Phoebe was our designer, and she was great. She sourced the exact diamond we had in mind and helped us find the perfect setting for it. She kept us up to date while we were on our travels, and the entire process felt seamless. I highly recommend Larsen Jewellery!

Georgia was amazing from day one!
Sourced a beautiful selection of diamonds for us to choose from. Walked us through the whole process and joined us in our engagement excitement! We are thrilled with my ring and can’t wait to come in to get our wedding rings.
The whole experience was superior and beautiful.
