Diamond Rings and jewellery Welcome to Polished Diamonds NZ - Engagement Rings and Fine Jewellery

Polished Diamonds New Zealand is an internationally recognised, award-winning New Zealand Jeweller that has the expertise to help with your choice of diamond engagement rings, wedding rings and fine jewellery. We create the diamond engagement rings that we sell and offer a lifetime guarantee along with an excellent price. 

We custom design each engagement ring or fine jewellery item using architectural computer aided design (CAD) producing flawless jewellery models prior to production. Clients then preview their unique ring in accurate proportion so they can decide on style adjustments to ensure it looks perfect prior to production. We then 3D print a wax/polymer model to bring the digital into physical and this is then invested into Platinum, Gold or Palladium - how cool is that?

As a factory-direct jewellery workshop we offer affordable pricing at the highest possible quality level. You can trust Polished Diamonds for our unmatched design, our commitment to excellence and for a personalised service at prices that will pleasantly surprise. Visit our design studio and view our range, browse online and be sure to read our blog articles and glowing customer testimonials. We also remodel, resize, polish and repair jewellery items. Call us on 0800-233-299 and ask direct questions - lets explore the options we are a friendly bunch that like to help.
