Whether you want to choose from one of our classic styles, or create something completely unique, Larsen Jewellery can make a 1 carat diamond engagement ring to suit any style. You can use our many display rings to help you choose a design, or alternatively, you can bring in your own ideas or pictures and our jewellers can help you design something special and truly your own.

We welcome you to come in for an obligation-free design appointment with one of our jewellers who can advise you on choosing an 1 carat diamond ring design to suit your individual style.

Carl Ume
We were so lucky to have found Ben at Larsen Jewellery. My partner had a unique engagement ring design and the minute Ben saw the reference photo he was confident he knew exactly what she wanted. To sit down with a jeweller (while watching another work in the studio) was completely different to the showroom/salesperson experience we had at other companies.

Ben knew what my partner wanted in terms of design but also clearly understood the style and feeling she was going for (if that makes sense). Dealing directly with the jeweller guided us on what would/wouldn’t work and we trusted Ben’s experience to bring out the best in the ring.

Any nervousness we had while waiting vanished when we saw the ring for the first time: stunning workmanship, the exact feeling/design my partner was going for and an incredibly natural fit. Luckily my partner fell in love with it the minute she saw it and over the last few months I believe she loves it even more as it slowly becomes a part of her.

It took us over a year to decide on who to entrust but from our first consultation at Larsen we knew we had finally found our place and it was all down to Ben’s experience, approach and love for his craft.

Thank you Ben and the Brisbane team.
Peter Le
What an incredible experience working with Larsen, especially Alex. Prior to coming to Larsen we visited about 8 different diamond boutiques in Melbourne, it was only here we were lucky enough to work directly with the person creating our engagement ring not just a salesperson.

From the get go Alex built trust with his knowledge and experience within the industry. We knew this was where we wanted to go and I immediately put a deposit down after our first consultation. We’re so happy with the result and I’m incredibly grateful for such a wonderful moment to have for the rest of our lives.

Ben was so friendly and professional, I was getting an engagement ring and had next to no clue what to ask for and Ben was amazing and so real throughout the whole process and explained it all very well including the finer details. Have and would 110% recommend to any friends/family/strangers looking to buy jewellery. Thankyou to all the team for making the engagement ring for my proposal stress free !
