We had a great experience with Jacinta and the team at Larsen designing our engagement band. Larsen was coincidentally our first appointment to discuss engagement rings and left us feeling confident and cared for as we were shown a wide variety of designs, artistry and jewels through which we were able to refine and craft a unique design that was perfect for us. The process gave us a feeling of confidence and quality from which it was easy to lock in further discussions. The final product matches the design we developed with Jacinta and looks stunning.

Got to work with Jacinta on our engagement and weddings bands, and couldn’t be happier with them! Such a good experience. The attention to detail, knowledge, and service from her and the team was top tier.

After a long and frustrating morning trying other jewellers, Ben was a huge breath of fresh air. Honest, unbiased, very patiently explained details to us. And we are absolutely thrilled with the end result. Could not recommend Larsen more.

Jacinta and the team at Larsen helped my wife and me pick out some fantastic ring designs and created rings that exceeded expectations. They helped us every step of the way and cannot thank Jacinta and everyone at Larsen enough.

Emma worked with us to turn a heirloom piece into my wedding band and earrings. She helped redesign and took us through our options, was super responsive, thorough and created beautiful outcomes. Our experience was 10/10, couldn’t recommend more!
