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.

Adrian Stroh
We had a fantastic experience designing & purchasing our ring with Soukata at Larsen Jewellery. She was very informative, communicated excellently and delivered an engagement ring which met our design and exceeded our expectations. 10/10 would recommend Soukata and the team to friends and family.
Bernice Bangcong
Larsen did a wonderful job with our engagement ring and wedding bands. Mimi Kind the jeweller is nice and friendly. She helped designed the engagement ring with my fiancé. We gave our set budget and we stuck with it. We also did the wedding bands experience which was really fun and educational. Highly recommend if you want the wedding bands to be intimate. You and your fiancé will do the ring making process, from the start to the end with supervision from the jeweller. Otherwise, 5/5!!!!
Teagan Comerford
Alex remodelled my engagement and wedding band into one piece. What he has created is incredibly beautiful. He listened to what I wanted and we collaborated to creative something I truly love wearing.
