Since 1969, Polished Diamonds has been a trusted name in creating bespoke diamond engagement rings and fine jewellery. With stores in Auckland, Wellington, and Christchurch, and our own dedicated workshop, we design, create, repair, and finish jewellery to the highest possible standard. Unlike companies that outsource to China or India with long 6-8 week production times, we create your custom jewellery right here in New Zealand in just 1-2 weeks. With the protection of the NZ Consumer Guarantees Act and our award-winning reputation, there’s no need to look elsewhere, visit the people that make it, for Quality, Trust and Sparkle.

Advanced Jewellery Design with CAD Technology

At Polished Diamonds, we use Computer-Aided Design (CAD) to bring your vision to life. Our advanced CAD technology allows you to preview your custom ring design with accurate finger sizing and precise gemstone measurements. You can make adjustments to ensure the design is perfect before production. Choose from styles such as:

• Classic solitaire
• Trilogy Diamond Rings
• Halo
• Multi-stone
• Filigree Vintage Rings

Once the CAD design is finalised, we create a 3D-printed resin prototype, which serves as the basis for a flawless casting. Using molten Platinum or Gold, our skilled craftsmen then hand-finish, polish, and detail the ring to ensure perfect symmetry and exceptional quality. The final piece is always error-free, precise, and backed by our lifetime workmanship guarantee. All finished in our award winning workshop.

High-Quality Diamonds and Gemstones for Every Budget

We supply a wide range of certified natural diamonds, coloured gemstones, and lab-grown diamonds to suit every budget. Whether you’re looking for a stunning engagement ring, a wedding band, or fine jewellery, we’ll work with you to create a piece that offers exceptional value and unmatched quality.
