Popular Diamond Ring Styles
Choosing an engagement ring should feel exciting, not complicated. At Polished Diamonds Christchurch, you can explore different diamond shapes, ring styles and precious metals in person while our team explains the differences that matter.
Compare classic solitaire designs with diamond-accent, halo, trilogy, vintage-inspired and contemporary rings, or use one of our existing designs as the starting point for something unique.
Choose from platinum, white gold, yellow gold, and rose gold, along with round brilliant, oval, emerald, radiant, pear, princess, cushion, marquise, and other diamond shapes.
We aim to help you create the right combination of design, diamond quality, proportions and budget, rather than simply choosing a ring from a display cabinet.

Custom Engagement Rings Designed in Christchurch
A custom engagement ring gives you control over the details that make a ring personal.
Our designers use professional Computer-Aided Design (CAD) technology to create an accurate three-dimensional model of your proposed ring. Detailed renders let you review the proportions, profile, setting, and diamond placement before manufacturing begins.
You can adjust the design during this stage, helping ensure the finished ring looks and feels exactly as intended.
Once approved, the design moves into production through our New Zealand jewellery workshop, where advanced manufacturing technology meets traditional jewellery skills, diamond setting, polishing, and hand finishing.
Whether you already know exactly what you want or have a few ideas, our Christchurch team can help develop them into a beautifully resolved piece of jewellery.

Natural & Lab-Grown Diamonds in Christchurch
Our Christchurch studio offers both natural diamonds and lab-grown diamonds, allowing you to compare the options and choose what is right for you.
We can explain diamond cut, colour, clarity, carat weight, proportions and certification in straightforward terms and help you balance the characteristics that have the greatest effect on beauty and value.
Certified diamonds are available with recognised grading documentation, including diamonds graded by GIA and IGI.
Lab-grown diamonds have the same fundamental crystal structure as natural diamonds but are created using advanced technology rather than forming naturally within the earth. They can offer significantly more diamond size for a given budget, while natural diamonds remain valued for their geological origin, rarity and history.
There is no need to decide before visiting. You can compare different diamonds and price points with our Christchurch team before choosing.
Wedding Rings Christchurch
Your wedding ring should complement your engagement ring as well as being comfortable enough to wear every day.
Polished Diamonds designs and makes women’s and men’s wedding rings in Christchurch, from refined traditional bands to contemporary designs, diamond-set wedding rings and completely custom pieces.
If your engagement ring has a low setting or unusual shape, we can use CAD to create a wedding ring that follows its contours precisely. Metals, widths, profiles, finishes and diamond details can all be adjusted to suit your preferences.
Couples can design their wedding rings together in our Christchurch studio, creating two individual rings that still share a connection through their materials, finish or design.

Jewellery Repairs, Remodelling & Ring Resizing Christchurch
Our Christchurch team can also help care for jewellery long after it has been made.
Bring your jewellery into our New Regent Street studio for assessment of ring resizing, jewellery repairs, stone-setting concerns, remodelling, restoration, polishing and general jewellery servicing.
Older or inherited jewellery can also be redesigned using CAD, allowing sentimental gemstones or precious metals to become part of a new piece while preserving the history behind them.
Having access to a dedicated jewellery workshop allows our team to assess jewellery properly and recommend the most appropriate solution rather than simply replacing an item.
