Carol Choi
Thank you Larsen for our beautiful and high-quality wedding rings! Working with Fleur was an absolute pleasure, she made the entire process so joyful and stress-free. Her patience and guidance through every step were truly appreciated. I’m especially grateful for her thoughtful design, as my wedding ring was custom-made to perfectly complement my engagement ring. It’s been just a month since our wedding, and my husband absolutely loves his ring—he can’t stop playing with it, haha!
Libby Taylor
We had a wonderful experience working with Georgia at Larsen to design and create my engagement ring. She was incredibly helpful, informative, and patient throughout the decision-making process, ensuring every detail was perfect. My ring is absolutely stunning!
Zach Giofkou
I highly recommend Larsen Jewellery. I was particularly impressed with how focused the experience was on designing the perfect engagement ring for me - I wasn't really sure what I wanted but Fleur worked through ideas with me and designed a really beautiful piece that my partner adores. They were not trying to upsell or lead me towards anything specific, but instead was committed to making sure I was happy with the design and cost. I wouldn't hesitate to go to Larsen again.
Constantin E. Dlaska
We had an amazing experience of making our own jewellery. The ring turned out so beautifully and better than we expect out of our hands. It was an interesting workshop with a lot of information and support for making the rings.The support via email prior and after the workshop was also excellent. We would recommend this to anyone who loves a personal touch to these important rings. Enjoy.

If you're looking to get a custom piece of jewellery made, or are just not sure what you are doing, I cannot recommend the team at Larsen Jewellery enough.My first experience with a jeweller (not at Larsen) to get a custom engagement ring made actually put me off getting something made quite a bit. It didn't feel like we were working towards the same thing and I would just be settling rather than getting what I was after.I was recommended Larsen and from the moment the process started it was different. Before my appointment I was already being asked questions to make sure they were ready, and once at my appointment Alex had already done up a beautiful sketch of a ring design based on the details I had provided.It was comfortable, supportive, seamless, it felt like Alex and the team were excited to make something with me and get it to be exactly what I was after or better. I was encouraged to ask questions, make criticisms or suggestions, use whatever materials I originally planned. This is all on top of the advice given with the design for practicality, insurance, safety etc.I will be coming back in future to get wedding bands made and look forward to going through the process again.
