David
Larsen were fantastic and Rachel was incredible throughout the process helping me navigate the design of the engagement ring. She made the process stress free, was so helpful and it was the best experience. It was a pleasure and one of the best decisions choosing Larsen as they made everything seamless. The engagement ring was super high quality and we couldn’t be happier with the result. I highly recommend Larsen and the team for a truly wonderful experience.
Katina Lehnert
Georgia was an absolute pleasure to work with. It took me some time to make a final decision, but she was incredibly patient, helpful, and understanding throughout the entire process. The presentation of the final ring was beautifully done thoughtful and elegant, complete with a lovely personal note. I can highly recommend this jeweller
Joe
Lovely experience! My wife had lost one of her favorite earrings at the beach and asked if I could replace it. After settling with Larsen, one of the jewelers Lulu walked me through options. They did a mold with the existing earring and handheld me to find that perfect color match (the most important thing)! Needless to say, the wife is over the moon and has been wearing them on the regular. Thanks again for the help, the patience and guidance was much appreciated!
Jarryd Cheso

James Mc Gourty
I had the absolute pleasure of working with Emma at Larson Jewelers to design the perfect engagement ring for my fiancée, Orla — and I honestly can’t recommend her highly enough.

From the moment I walked in, Emma was incredibly friendly, approachable, and made the entire experience feel exciting and personal. She immediately understood the vision I was trying to describe and helped bring it to life with such creativity and attention to detail.

Emma’s warmth, patience, and genuine enthusiasm made the process very easy.The ring turned out better than I ever could have imagined — and Orla absolutely adores it.

If you’re looking for someone to help you create a ring that reflects your love story, Emma is the person you want by your side. Thank you so much, Emma, for your kindness and expertise.
