Chris W
Went in at short notice to find a wedding present for my fiancee. The staff were very helpful and informative including sending the earrings I wanted down from Brisbane to view so I could see them before deciding to purchase. Thanks to Alex for his help. Most importantly, fiancee now wife very happy.
Yaan Kit Ng
Going with Larsen to create our engagement ring was the best decision we made! They provided such a supportive and helpful experience throughout the whole process. We connected with Fleur and she was so knowledgeable and friendly. She expertly guided us through the ring customization process, and was able to translate our ideas into the perfect ring. We highly recommend Larsen to all our friends and anyone looking to create a lifelong piece!
Michael Lambevski
We had our engagement ring made at Larsen Jewellery and were very impressed by the experience. Georgia guided us through each step with care and thought. The craftsmanship of the ring is truly remarkable. Highly recommend Georgia and the team at Larsen
Akintola
My partner and I decided to go on a tour of melbourne jewellers and stumbled across Larsen towards the end of our day. We were looking for a custom made engagement ring and this place blew every other place out the water - admittedly we were a but intimidated walking into the place but were instantly made to feel at ease by Alex who handled the situation incredibly well.

We had a brief idea of what we wanted but Alex asked all the right questions and showed us different compositions and ended up sketching the ring for us and ordering in some stones, all before we paid a cent. We then went in when the stones arrived and OMG. It was perfect, I paid the deposit on the spot, and Bang - the *INCREDIBLE* ring was ready after a couple of months! I cant thank you enough for such an amazing experience. If anyone is thinking about getting a bespoke ring made to fit at a really solid price, don’t hesitate to give these guys a visit!

Thanks again guys! 🫶 1000/10

My partner and I have had the pleasure of being taken care of by Alex, he really understood the assignment which made my dream come true, I'm ecstatic with my new earrings, the quality, price, and customer service here at Larsens is truly incomparable!
Li Ann Lee
Alex did an amazing job with my engagement ring and picked out the most beautiful coloured diamond for me. I would go to Larsen and Alex again for future pieces
