We offer outstanding men’s wedding rings, from contemporary Titanium and Zircon to timeless Platinum and Yellow Gold. We can craft any shape, finish, and profile you desire to perfection.
Natural & Lab-Grown Diamonds
Natural Diamonds are our area of expertise, and we offer a diverse selection of certified and ethically sourced options, with over 30,000 available in our inventory. Natural diamonds are appreciated, rare, and, as they say, “A Diamond is Forever.” Our certified diamond grading team can help you discover your ideal diamond.
Lab-grown diamonds are popular as they can be priced up to 75% lower while maintaining visual and aesthetic parity with their natural counterparts. Similar to the distinction between ice in a freezer and ice in a glacier, there is no chemical or material difference, only the creation method. We are equipped to set any lab-grown diamond into our jewellery pieces, providing a cost-effective sparkle that remains a genuine diamond.
Fine & Luxury Jewellery

Advanced CAD Jewellery Design
At Polished Diamonds, your perfect ring becomes a reality with our advanced Computer-Aided Design (CAD) technology.

This enables you to make style adjustments until it’s exactly as you imagined. Choose from classic styles like:
- Solitaire Engagement Diamond Rings
- Trilogy Diamond Rings
- Halo Diamond Rings
- Vintage Diamond Rings
You can even try on a 3D-printed resin model before your ring is made, giving you confidence in the design, proportions and comfort. Our skilled artisans then expertly hand-finish, polish, and detail the ring to perfection. The final piece is not just beautiful; it is meticulously crafted to be error-free and precise, backed by our lifetime workmanship guarantee – all perfected in our state-of-the-art NZ workshop. Trust us to turn your vision into a perfect reality.
