Virginie Gueret
We went there to have our engagement ring made. We didn't really have our mind set on a specific design and changed direction a couple of times but Rachel was very lovely, professional and patient in helping us choosing. We felt really comfortable, not rushed and it was really fun to try different designs. The result is beautiful and we love it! 😀

We went back for our wedding bands and we are both delighted by the result! Plenty of compliments post wedding day!
Brett Hay
Georgia was very helpful in assisting me with choosing an engagement ring. Good people and great service!

Highly recommend the team at Larsen Jewellery.
Ben Bond
Fleur was an absolute delight to deal with to secure the perfect engagement ring for my now fiancée. We initially had a joint consultation before working with Fleur individually to choose the diamond and design the band.

Her experience and professionalism was evident through her patient and caring approach, along with constant communication and progress updates along the way.

I would recommend Larsen Jewellery and Fleur 100% to anyone in my network.
Bryn Hodgson
My wife and I were fortunate enough to come across Larsen Jewellery after struggling to find a jeweller who could bring our vision to life. We had found a specific wedding ring design online which involved setting each other birth stones the entire width of the ring (an aquamarine and sapphire), but it was only Ben at Larsen Jewellery that said he would do it.

From the very beginning, Ben was incredibly helpful, assuring us that the design was possible and guiding us through every step of the process. He kept us informed throughout the design and construction, making what could have been a stressful experience truly enjoyable. The pricing was also very competitive, which was a great bonus.

We couldn’t be happier with the final result. The craftsmanship is stunning, and the ring is exactly what we hoped for and more. We’re so grateful to Ben and the entire Larsen team for their expertise, professionalism, and care.

We now have the perfect rings to last us a lifetime, and we wholeheartedly recommend Larsen Jewellery to anyone looking for high-quality, custom-designed pieces.
Lara Mitchell
Georgia at Larsen Jewellery was absolutely fantastic! I came in with a brief on what I wanted for my wedding band and she helped me find something that perfectly matched my enagagement ring. We then came back to design my husband's wedding band too and again, it was exactly how he wanted it and the process was seemless. Greater quality, greater experience and better priced than any 'off the table' options at the other jewellers. Can't recommend Larsen Jewellery enough.

EMMA IS THE BEST !!!
From start to finish the process at larsen’s was so easy. Emma was honest and so helpful throughout the process in finding the perfect ring for my Fiancé. The end product was exactly what I wanted. I couldn’t recommend them enough.
