About RoCS

Our studio and workshop are based in the heart of Richmond at 238a Queen Street.  

Brett has over 17 years’ experience in the jewellery industry and a passion for designing.  He is the only qualified gemmologist in the top of the South Island, with a diamond grading qualification, and one of the few in New Zealand with a diploma in Diamond Technologies.  So, for a true expert opinion on diamonds and gemstones come to the studio that other jewellers come to for help.

Our experienced team are there to help, we are happy to talk you through the design process, discuss options for new pieces, re-makes or repairs, and provide quotes for different alternatives, then you can make an informed decision on how you'd like to proceed with your jewellery requirements.

Whether you are looking for a classic diamond engagement ring, or something that is uniquely yours, we are definitely the jewellers to come and see.
