Why Polished Diamonds?

Polished Diamonds has been a trusted business since 1969, specialising in designing and creating diamond engagement rings and fine jewellery. We have shops in Auckland, Wellington, and Christchurch, where customers can visit and explore in a relaxing and informative environment. We have won several awards, including Best Retail Business, Best Engagement & Best Wedding Ring Designs.

Every piece of jewellery we create is unique and custom-made, especially for you, and not a ‘cookie-cutter’ item made overseas. We use advanced Computer-Aided Design (CAD) technology to showcase how your ring will actually look using the finger size and diamond/gemstone measurements. This allows you to make design adjustments to ensure it is perfect. You can select engraving, filigree, single or multi-stone, halo or the classic solitaire ring styles. After finalising the CAD 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, wedding ring or fine jewellery item 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.

We use Computer-Aided Design (CAD) to produce every unique ring that we sell.  This software enables us to showcase any style you like to your finger size and using the actual gemstone measurements.  Clients can email us photos of their favourite design and we can add in engraving, filigree, side diamonds and any style adjustments to personalise the ring image.  We email this CAD file for client approval before manufacture.
