Diamond Rings and Fine Jewellery NZ... since 1969

Why Polished Diamonds?

Polished Diamonds is a reputed brand that specialises in designing and manufacturing custom-made diamond engagement rings and fine jewellery. With showrooms in Auckland, Wellington, and Christchurch, we have been in business since 1969 and have won several awards for our excellent value and highest quality of jewellery.

We guarantee that every piece of jewelry we create is unique and custom-made specifically for you, and not a cookie-cutter chain store item made overseas. We use advanced Computer-Aided Design (CAD) technology to showcase how your ring design will look using the finger size and diamond/gemstone measurements. This allows you to make tuning adjustments to ensure it is perfect. You can select engraving, filigree, single or multi-stone, halo or the classic solitaire. The CAD model will show you a preview of exactly how the ring will look finished. After finalizing the design, we produce a resin copy of the ring using a 3D printer. This prototype is used to invest in casting material, and we then inject the molten Platinum or Gold into the mould to perfectly replicate your ring. Before setting the diamond or gemstone, we hand detail, polish, and prepare the ring with our skilled craftsmen in our workshop. This ensures that we deliver an error-free, accurate, and perfectly symmetrical diamond ring that is unbeaten in quality – backed with a lifetime workmanship guarantee.

We can supply any certified natural diamond, coloured gemstone, or lab-grown diamond within your budget. Polished Diamonds can then design and produce the ideal ring, resulting in excellent value and the highest quality. We have won multiple awards for our quality proposition, and we invite you to contact us, visit a shop, and experience our service.
