Jessie Pham
Alex assisted me with organising the most beautiful diamond earrings 2ct total weight for my partner, he also educated us on the diamond grading which was so insightful! Alex is an expert and he explained everything so well. Thank you Alex!
Vibol Leng
It was a lovely experience purchasing from Larsen. Jacinta was very personable, knowledgeable and made the process so easy. And the ring itself is stunning! Highly recommended.

Peter & Selda
Carol Chen
Emma is very helpful throughout the process and the rings came out beautiful.
Anna Kneipp
I recently had a custom ring made at Larsen, and my experience was fantastic. I shared my ideas for the setting and stones with Ben, who patiently walked me through the options and created hand drawn sketches. He was kind, very responsive, knowledgeable, and made sure I understood every step of the process. We ended up changing one of the gemstones once the ring was already completed, and the adjustment was handled quickly and seamlessly. I couldn’t be happier with the result - highly recommend!
Rob Barton
As usual we left Larsen's after having had great interactions with the staff, and superb craftsmanship. We would recommend them to anyone.
