Yasmeen F
For engagement rings, this is the BEST place! We visited a few shops around (including one very very nearby), and Larsen was hands down the best. We had our appointment with Ben, who was an amazing help throughout the selection process. The point of difference for us was that Ben was the actual jewelry maker, which meant we could lean on him for his expertise and you could tell he genuinely cared. Out of all the shops we went to, Larsen sourced the best looking stones and made the process fun. The showroom is beautiful too. Cannot recommend enough!
Chris Penfold
Soukata was amazing to work with. She was so patient throughout the whole process, helping me design a Toi et Moi ring that my fiancée absolutely loves. I wasn’t always sure what I wanted, but she guided me with thoughtful suggestions and never rushed anything. The final ring turned out beautifully—elegant, personal, and exactly what I was hoping for. Highly recommend Larsen to others!
Justin Le
Amazing ring for our special moment! Great service as the team was doing there best to help me to get the ring I wanted in such a tight timeline.
Brittany Reeves
Soukata did an amazing job helping to design my engagement ring and our wedding rings. We absolutely loved our experience at Larsen - nothing was too much trouble and all their jewellery is just beautiful.
Mitchell Tan
I was referred to Larsen by a friend who highly recommended Alex Sommerville services. I am shocked and amazed at his level of expertise, professionalism and passion for his craft.

Alex custom designed a ring that had all the features that my partner has been hinting at, he took all the suggestions that I had and custom designed an absolutely beautiful ring. Not only that, but he managed to find a diamond that exceeded all my expectations and ended up being cheaper than what I had originally budgeted.

I would highly recommend Larsen and in particular Alex's services to anyone who is looking to buy their partner the ring they deserve. If luck is on my side, this will be the only time I ever require their services, so I can only hope to recommend them to as many people as possible.
Chelsea Collins
Jacinta worked with me and my husband Chris to design our engagement rings and later our wedding bands - I can't recommend her highly enough. Jacinta is incredibly kind, encouraging, and passionate about jewellery. We felt so at ease with her from the moment we met, and she listened to us and asked all the right questions to fully understand our vision for our rings. From the first appointment for our engagement rings to the pick-up appointment for our weddings bands we have felt completely supported by her and trusted her fully to make sure our rings were perfect (which she absolutely did).

I'm a creative person and I've previously worked in jewellery design, so I can be quite particular about what I want and what I think looks cohesive and well balanced - I never had to worry about that with Jacinta. Her eye for angles and aesthetic balance meant that she never showed us a single stone that wasn't beautifully proportioned and the perfect scale for our design goals.

We love our rings so much, I doubt a week has gone by since we got engaged that we haven't talked about how much we love them. My husband first proposed in May 2023 and I get compliments and questions about my engagement ring all the time.

I could write a book about how much we loved working with Jacinta, so I better wrap it up - I would recommend Larsen and Jacinta to absolutely anyone, the quality of their work is exceptional.
