Tyler Stross
We absolutely love the Bracelet and Rings we have purchased from Larsens. The jewellery is great value and of exceptional quality. The staff are extremely friendly and helpful. We were able to customise each piece to be unique and special. Highly recommended!
Jane Spencer
Having my 40 year old engagement ring remodeled by Emma and the team at Larsens went so well. Emma's creativity is very impressive and I am so happy to be enjoying my diamonds in a much more modern and stylish way!!!!!Thank you all !!!!
Jessica L
We custom designed a diamond engagement ring at Larsen and had an amazing experience with Fleur and the team. Fleur was not only very knowledgeable and warm but most importantly, was so patient listening to what we wanted and working with us through all the details of the design. We were indecisive about some aspects and were so glad to have Fleur's expert guidance to help us decide what we wanted.We felt the team genuinely cares about making sure we get the most beautiful and high quality ring possible. We would definitely highly recommend Larsen to anyone looking for a jeweller to help you design your perfect ring!
Daniel Smith
Had a fantastic experience with Larsen jewellery. Jacinta was knowledgable, patient and respectful throughout the whole ring choosing process which made my experience a whole lot more simple. My now fiancé is absolutely over the moon with her engagement ring and we both couldn't be happier with how everything turned out. Big thanks once again to Jacinta and i would totally recommend Larsen for anyone’s Jewellery needs!
Kate Tran
Great experience with Fleur who helped us with the design and delivery of my eternity band
Andrew Rappos
Absolutely thrilled with the entire experience working with Fleur to design a custom engagement ring for my partner! From start to finish, Fleur was incredibly helpful, informative, and communicative, making the process smooth and enjoyable. She took the time to truly understand my vision and brought it to life in such a unique and beautiful way. I never felt rushed or uncertain, as Fleur was always there to answer my questions and guide me through each step. The final result is beyond anything I could have imagined—it's truly a one-of-a-kind piece that captures the essence of our love perfectly. I couldn't recommend Fleur more highly. If you're looking for someone who not only creates stunning jewelry but also makes the entire experience enjoyable and stress-free, look no further!
