Precious Metals for Rings: Platinum, Gold and Other Options
Choosing the right precious metal is an important part of selecting or designing a ring. The metal affects the colour, weight, durability, maintenance requirements and overall character of the finished piece.
For engagement rings and wedding rings in New Zealand, the most popular precious metals are platinum, white gold, yellow gold and rose gold. Palladium is another naturally white precious metal, although it is now used less frequently.
At Polished Diamonds, we create diamond rings, women’s wedding rings and men’s wedding rings in a range of metals. The best choice depends on how you want your ring to look, feel and wear over time.
Which Precious Metal Is Best for a Ring?
There is no single best metal for every ring. The right choice depends on the design, lifestyle, colour preference and how much ongoing maintenance you are comfortable with.
| Metal | Appearance | Best Known For |
|---|---|---|
| Platinum | Naturally white | Density, durability and low colour maintenance |
| White Gold | Bright white | Traditional gold with a white finish |
| Yellow Gold | Warm yellow | Classic colour and timeless appearance |
| Rose Gold | Pink to blush | Distinctive warm colour |
| Palladium | Naturally white | Lightweight platinum-family metal |
For engagement rings, diamond settings and wedding rings intended for everyday wear, the practical differences between these metals are worth understanding before making a decision.
Platinum Rings
Platinum is naturally white, dense and highly suited to jewellery that will be worn every day.
Unlike white gold, platinum does not require rhodium plating to achieve its white colour. Over time, the metal develops a soft surface patina. You can leave this unique character intact or ask our master jewellers to professionally polish it back to a high shine.
Platinum also feels noticeably heavier than gold because of its greater density. Some people particularly like this substantial feel in a wedding ring or men’s ring.
Its naturally neutral colour makes platinum especially popular for diamond engagement rings because it does not introduce additional colour around a white diamond.
White Gold Rings
White gold is created by alloying gold with other metals to produce a lighter-coloured metal.
Because pure gold possesses a natural yellow hue, jewellers apply a rhodium plating to white gold to create the crisp, bright white finish most people expect.
Rhodium gradually wears with everyday use, so white gold rings can require periodic replating to maintain their bright finish.
White gold remains a popular option for engagement rings and wedding rings where the wearer prefers gold but wants a white-metal appearance.
Yellow Gold Rings
Yellow gold has been used in jewellery for centuries and remains one of the most recognisable precious metals.
Its warm colour works particularly well in both classic and contemporary wedding rings and can provide a striking contrast against white diamonds.
Metallurgists alloy pure gold with other metals to give it the durability and working characteristics required for fine jewellery. The carat describes the proportion of pure gold within the alloy.
For example:
- 18kt gold contains 75% pure gold.
- 14kt gold contains 58.5% pure gold.
- 9kt gold contains 37.5% pure gold.
Higher-carat yellow gold generally has a richer gold colour, while lower-carat gold contains a greater proportion of alloying metals.
Rose Gold Rings
Rose gold is created by combining gold with metals including copper, producing its characteristic pink or blush colour.
The exact tone depends on the alloy and the proportion of gold used.
Rose gold can work beautifully for engagement rings, wedding rings and matching bridal sets. Our craftspeople can also use rose gold selectively within a two-tone ring to introduce subtle warmth and striking contrast.
For men’s wedding rings, our master jewellers combine rose gold with white gold, platinum, or alternative metals like zirconium to craft a strikingly contemporary two-tone design.
What About Palladium?
Palladium belongs to the platinum family of metals. It is naturally white and considerably lighter than platinum.
It does not require rhodium plating and was previously a popular alternative to platinum. Today, however, clients less commonly select palladium because availability, manufacturing constraints, and future repair considerations make platinum or gold far more practical choices.
For someone looking for a naturally white precious metal, platinum and white gold are usually the first options worth comparing.
Precious Metals for Men’s Wedding Rings
Metal choice is especially important when selecting a men’s wedding ring because width, thickness and weight can significantly affect how the ring feels on the hand.
Platinum creates a substantial, weighty ring, while gold generally feels lighter. Yellow and rose gold create a warmer appearance, while white gold and platinum provide a more understated white-metal finish.
Men’s rings can also combine precious metals with materials such as titanium or black zirconium to create two-tone designs, contrasting inlays or more contemporary finishes.
The profile of the ring is equally important. Flat, curved and shaped bands can feel very different even when made from the same metal.
Should Engagement and Wedding Rings Be the Same Metal?
Not necessarily.
Choosing the same metal creates a consistent colour and uniform wear pattern; however, deliberately pairing mixed metals produces a strikingly harmonious contrast.
The more important issue is how the two rings physically meet. A wedding ring that continually rubs against claws, settings or delicate details can cause wear regardless of the metals chosen.
When we design an engagement ring using CAD, we can consider how a future wedding ring will sit alongside it before the engagement ring is manufactured.
Which Metal Should You Choose?
Choose platinum if you want a naturally white, substantial precious metal with minimal colour maintenance.
Choose white gold if you prefer gold but want a bright white appearance.
Choose yellow gold if you want a traditional warm gold colour.
Choose rose gold for a distinctive pink or blush tone.
For a wedding ring, also consider the width, profile and overall weight of the design. These factors can influence everyday comfort just as much as the metal itself.
Custom Rings Made in New Zealand
Polished Diamonds designs and manufactures engagement rings, wedding rings and custom jewellery through our New Zealand jewellery workshop.
Using CAD jewellery design, we can control the proportions, dimensions, setting and profile of a ring before manufacture. This is particularly useful when creating matching wedding rings, wider men’s wedding bands or custom two-tone designs.

Precious Metal FAQs
Platinum is naturally white and does not require rhodium plating. White gold provides a similar appearance but generally requires periodic replating. Both can be excellent choices depending on the design and wearer.
Yes. Platinum is particularly well suited to men’s wedding rings where a substantial weight and naturally white colour are preferred.
There is no universal best choice. 18kt, 14kt and 9kt gold contain different proportions of pure gold, which affects colour, composition and price. The design and how the ring will be worn should also be considered.
Yes. Mixed-metal bridal sets can work very well. The important consideration is ensuring the rings are designed to sit together without unnecessary rubbing against settings or claws.
Gold and platinum remain the principal precious-metal choices. White gold, yellow gold and rose gold provide different colours, while platinum offers a naturally white and relatively low-maintenance alternative.
