Diamond Rings

Polished Diamonds designs and crafts diamond rings in New Zealand, combining certified diamonds, advanced jewellery technology and skilled local craftsmanship. Whether you are choosing an engagement ring, celebrating a special occasion or creating something completely unique, our team can help you find a design that suits your personal style, lifestyle and budget. Creation takes 1-2 weeks in our NZ workshop.

Our rings are available with natural or lab-grown diamonds, providing flexibility across diamond size, quality, origin and price. We can guide you through the 4Cs—cut, colour, clarity and carat weight—as well as diamond proportions, brilliance and overall appearance. This helps you choose a diamond based not only on its grading report, but also on how it will look in the finished ring.

Choose from platinum, white gold, yellow gold or rose gold, with every design able to be personalised. Our custom diamond ring design service uses CAD technology to produce detailed digital renders before manufacturing, allowing the proportions, setting and finer details to be reviewed and refined. We can also 3D-print a resin copy to try for added assurance.

With walk-in jewellery showrooms in Auckland, Wellington and Christchurch, Polished Diamonds provides personal service to customers throughout New Zealand.

Diamond Rings Frequently Asked Questions

How do I choose the right diamond ring?

Start by considering the wearer’s personal style, preferred diamond shape, ring setting, metal and your available budget. Next, compare diamonds using the 4Cs: cut, colour, clarity and carat weight. Polished Diamonds can help you compare suitable options and create a custom diamond ring that balances appearance, quality, practicality and price.

What are the 4Cs of diamond quality?

The 4Cs are cut, colour, clarity and carat weight. Cut influences how effectively a diamond reflects light and sparkles. Colour measures how colourless a white diamond appears, while clarity evaluates inclusions and surface characteristics. Carat measures the diamond’s weight rather than its visible dimensions. The best combination depends on your budget and personal priorities.

What diamond ring styles can I choose from?

Popular diamond ring styles include solitaire, solitaire accent, halo, trilogy (three-stone), vintage, eternity, and anniversary rings. A solitaire highlights one central diamond, while halo and accent designs add extra sparkle. Trilogy rings feature three principal stones, and vintage designs use decorative details inspired by earlier jewellery periods. Every style can be customised.

Which diamond shape should I choose?

Choose a diamond shape that suits the wearer’s style rather than following a single rule. Round brilliant diamonds offer a classic appearance and strong sparkle. Oval, pear and marquise diamonds create an elongated look. Emerald and Asscher cuts produce broad, elegant flashes of light, while princess, cushion and radiant diamonds offer distinctive geometric alternatives.

Which diamond shape looks the largest?

Elongated diamonds such as oval, pear and marquise shapes can appear larger from above than some round diamonds of the same carat weight. However, carat weight does not determine visible size on its own. A diamond’s measurements, proportions, depth and setting all affect how large it appears on the finger. Consider using Lab-Diamonds to enable a larger size within yoiur budget.

Are lab-grown diamonds real diamonds?

Yes. Lab-grown diamonds are real diamonds with essentially the same chemical composition, crystal structure and physical properties as natural diamonds. The principal difference is their origin: natural diamonds form in the earth, while lab-grown diamonds are produced under controlled conditions. Both can be independently graded for cut, colour, clarity and carat weight.
