I recently had two rings made by Rod at Larsen Jewellery.He was wonderful and made the process very simple and enjoyable. I am delighted with the end result. They are exactly what I envisaged and I cannot thank Rod enough for his expertise, time and effort.

I can't say enough amazing things about Larsen Jewellery! When I inherited my grandma's opal ring, I wanted to turn it into a necklace to preserve its sentimental value. After stumbling upon Larsen Jewellery online, I sent an inquiry and got a response within 24 hours. Ben, the gem behind my experience, not only knew what mine my grandfather mined the opal but also sketched out the perfect necklace and offered beautiful suggestions. The whole process was a breeze, and my beautiful necklace was ready in just 5 weeks. Seeing my grandma tear up at its beauty made it all worth it. Huge thanks to everyone at Larsen Jewellery, especially Ben! I'll be shouting your praises to everyone I know!
