Brittany Rae
I couldn’t be happier! My partner and I began the engagement ring process together at Larsen Jewellery with Emma, who helped bring my vision to life. She listened to my ideas, offered her expertise, and after I stepped back so the proposal could be a surprise, she guided my partner through the rest of the process. The result was everything I dreamed of and more!
Sam
I cannot recommend Larsen Jewellery enough. I came here for an engagement ring with a certain idea in mind and Celeste helped me create a piece that was exactly what I was envisioning. Throughout the whole process she was so enthusiastic and her attention to detail was amazing. Thanks to both Larsen and Celeste I was able to give my now fiancée a truly wonderful ring!
Robert K
I had a fantastic experience with Jacinta from Larsen in creating my partner's custom ring. I had spoken to many jewellers prior to Larsen and Jacinta was the first person who filled me with confidence and affirmation that they knew what they were doing. Communication was excellent and the turn around from start to finish was fantastic. Every step of the way was met with positivity and the attention to detail was second to none.

I cannot thank you guys enough for creating the perfect ring and memories for us
Jack Hure
I cannot say enough about the diligence, effort and transparency of Larsen Jewellers. They created the most beautiful engagement ring for my partner, and were amazing throughout the entire process. Whether you know very little, or a good deal about jewellery, they are wonderful and make you feel welcome, heard and confident. I could not recommend them any more, they are my most trusted jeweller now.
Kerri-Lee George
My partner and I did the make your own wedding band experience and it was amazing!!! Jason was a patient and fun teacher and the rings we made are beautiful. I can’t wait to wear them once we get married next month. The experience has left us with such a lovely memory to have connected to our rings.
Matt L
I am very grateful to Jason and the team at Larsen for their patience and professionalism. As someone with no prior experience in choosing engagement rings, I truly appreciated their expert advice and guidance every step of the way. Communication was excellent, and they were attentive throughout the entire process, making what could have been overwhelming feel smooth and enjoyable. Their helpfulness and care made the experience stress-free and unforgettable.
