Types of Engagement Rings: A New Zealand Buyer's Guide to Styles and Shapes

Style vs Shape: The Two Choices That Matter

People often use “type” to mean two different things, so it is worth separating them. The style is the setting design — a solitaire, a halo, a trilogy, and so on. The shape is the cut of the centre diamond — round, oval, emerald, and the rest. You choose one of each. An oval diamond in a halo setting, for instance, is a completely different ring from an oval solitaire, even though the diamond is the same shape.

We will cover the styles first, then the shapes.

Engagement Ring Styles

Solitaire

The solitaire is a single diamond on a plain band — the most recognised engagement ring in the world. Its appeal is timelessness: nothing distracts from the centre stone, and the design never dates. Because the diamond does all the work, the 4Cs matter most here. Best for anyone who loves understated, classic jewellery.

Halo

A halo ring frames the centre diamond with a circle of smaller stones, making it look larger and adding serious sparkle. It is one of the most popular styles in New Zealand because it delivers maximum visual impact for the budget. Cushion, oval and round centres all suit a halo beautifully. Best for those who love sparkle and presence.

Trilogy (Three-Stone)

A trilogy ring sets three diamonds across the band, traditionally symbolising the past, present and future of a relationship. The look is rich and meaningful, spreading light across three points rather than concentrating it in one. Best for those who value symbolism and a ring that tells a story. We compare these three styles in detail in our solitaire vs halo vs trilogy guide.

Dress & Multi-Stone Rings

Beyond the three classics, dress rings and cluster or multi-stone designs offer bolder, more individual statements — ideal as a striking alternative engagement ring or a standout right-hand ring. These suit buyers who want something distinctive rather than traditional.

Engagement Ring Shapes

Once you have a style in mind, the shape of the centre diamond sets the tone. Here are the six most popular shapes in New Zealand. For a deeper visual comparison, see our full diamond shapes guide.

Marquise, radiant and other shapes are also available — our jewellers can source and set almost any cut you have in mind.

Don't Forget the Metal

Every style and shape can be made in platinum, white gold, yellow gold or rose gold, and the metal changes the whole feel of the ring. If you are weighing up the options, our metal comparison guide breaks down durability, cost and colour for New Zealand buyers.
