Wedding Rings

Wedding rings should embody strength, durability, and stunning beauty—just like a successful marriage. We expertly design and craft each wedding ring tailored to our client’s individuality. Whether you seek a classic style, a diamond set, modern aesthetics, or something uniquely different, we have you covered. Explore our exceptional range and reach out for custom options that reflect your vision.

For women’s wedding rings, we offer the innovative service of laser scanning your existing engagement ring, ensuring we match the width, depth, and profile for a flawless ring set—how incredible is that? Visit your local store to find the perfect wedding ring to complement your engagement piece.

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.

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.

Gemstones

Vibrant colours are represented in the wonderful world of gemstones. From blue sapphires to light pink morganite and forest green garnet, we can supply almost any colour, shape, and gemstone variety. Explore information about coloured gemstones and contact to explore the options.

With walk-in shops in Auckland, Wellington, and Christchurch and our skilled in-house workshop, we design, create, repair, and finish each piece to the highest possible standards. Unlike many jewellery companies that outsource production to countries like China or India, resulting in lengthy wait times of 6-8 weeks, we proudly design and produce in just 1-2 weeks. With the assurance of the New Zealand Consumer Guarantees Act and our award-winning reputation, there’s simply no reason to look anywhere else. Visit us today to discover the perfect combination of Quality, Trust, and Sparkle!

Advanced Jewellery Design with CAD Technology

At Polished Diamonds, your perfect ring becomes a reality with our advanced Computer-Aided Design (CAD) technology. With CAD, you can visualise your custom ring design with accurate finger sizing and gemstone measurements for perfect proportion. 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

Once you confirm the CAD model, we will create a 3D-printed resin prototype to ensure flawless casting. You can also try it on before manufacturing—how cool is that! 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.
