Dylan Choy
Quick and easy jewellery purchase, made easier through fantastic service and answering my many questions. I really appreciated everything from Georgia who got me through the purchase!
Madeline Cairns
We had a beautiful experience choosing and designing our wedding rings with Jacinta and the team at Larsen Jewellery! Highly recommend
Leah Jones
We are thoroughly impressed with Larsen Jewellery. Jacinta (go see her, she is amazing) designed three custom pieces for us, and each one exceeded our expectations. From the very first consultation, she took the time to understand exactly what we wanted and brought our vision to life, bringing her own unique skills and creativity. The entire process was smooth and enjoyable, and the final pieces are truly stunning - unique, meaningful and beautifully made. Thank you for creating something so special. We couldn’t be happier! We will be returning in the future.
Rachel Rios
