Engagement Rings & Fine Jewellery … since 1969

Every ring from Polished Diamonds is custom-made specifically for you, not a cookie-cutter chain store item made overseas. We use Computer-Aided Design (CAD) to showcase how your ring design will look using the finger size and diamond/gemstone measurements. You can select engraving, filigree, single or multi-stone, halo or the classic solitaire. You can have any ring design. The CAD model will show you a preview of exactly how the ring will look finished. This allows you to make tuning adjustments to ensure it is perfect.

We then send the CAD file to a 3D printer and produce a resin copy. This prototype is used to invest in casting material, and we then inject the molten Platinum or Gold into the mould and your ring is then perfectly replicated. Before setting the diamond or gemstone, we hand detail, polish and prepare the ring with our skilled craftsman in our workshop. Technology meets traditional craftsmanship, resulting in 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 diamond for your budget. Polished Diamonds can then design and produce the ideal ring style for your diamond resulting in excellent value and the highest quality. We have won multiple awards to back our quality proposition and invite you to Contact Us and experience our service.
