Why Choose Yellow Gold for a Diamond Ring?
Yellow gold is one of the most recognisable precious metals in fine jewellery and provides a naturally warm setting for diamonds.
Unlike white gold, which is alloyed to create a paler colour and is commonly rhodium finished, yellow gold retains the characteristic colour associated with gold itself.
That warmth can create a particularly attractive contrast with a white diamond. Rather than visually blending with the gemstone, as platinum or white gold can, the yellow band becomes an intentional element of the finished design.
Yellow gold can also suit a wide range of aesthetics. A simple solitaire diamond ring can look refined and contemporary, while intricate details, accent diamonds and vintage-inspired settings can give yellow gold a more traditional character.

9kt, 10kt, 14kt, 18kt or 22kt Yellow Gold?
The kt designation describes how much pure gold is contained within the alloy.
Polished Diamonds can manufacture yellow gold jewellery in several different purities:
- 9kt yellow gold – 37.5% pure gold
- 10kt yellow gold – approximately 41.7% pure gold
- 14kt yellow gold – approximately 58.5% pure gold
- 18kt yellow gold – 75% pure gold
- 22kt yellow gold – approximately 91.7% pure gold
The remaining proportion consists of other metals used to create an alloy suitable for jewellery manufacture.
The higher the gold content, the more the characteristics of pure gold influence the alloy. This affects colour, price, weight and how the metal behaves in a particular ring design.
9kt Yellow Gold
9kt yellow gold contains 37.5% pure gold and a greater proportion of alloying metals.
It provides an accessible genuine-gold option and can be a practical choice when balancing the precious metal, diamond specification and total ring budget.
10kt Yellow Gold
10kt yellow gold contains approximately 41.7% pure gold.
Sitting between 9kt and 14kt, it gives another option for clients looking to balance gold content, appearance and price.
14kt Yellow Gold
14kt yellow gold contains approximately 58.5% pure gold and offers an attractive balance between gold content, colour and practical suitability for everyday jewellery.
It works particularly well across engagement rings where both fine setting detail and long-term wear need to be considered.
18kt Yellow Gold
18kt yellow gold contains 75% pure gold and has a richer gold content than 9kt, 10kt or 14kt.
It has a strong tradition in fine jewellery and is an excellent option for clients who value higher gold purity and a richer yellow-gold appearance.
22kt Yellow Gold
22kt yellow gold contains approximately 91.7% pure gold, giving it a particularly rich and distinctive gold colour.
Because its gold content is much higher, 22kt is also more malleable than lower-carat gold alloys. This means the suitability of 22kt should be considered in relation to the individual ring design, particularly where very fine claws or delicate setting components are involved.
Our jewellery designers can advise whether 22kt is appropriate for the ring you are creating or whether a lower-carat yellow gold or two-metal construction would provide a better technical solution.
Yellow Gold vs White Gold, Rose Gold and Platinum
Choosing a precious metal affects far more than the colour of an engagement ring.
White gold diamond rings provide a bright neutral appearance and allow a white diamond and its setting to visually blend together.
Rose gold diamond rings introduce warmer pink and copper tones for a softer and more distinctive appearance.
Platinum diamond rings use a naturally white, dense precious metal and provide a noticeably substantial feel on the finger.
Yellow gold creates the strongest traditional gold colour and an intentional contrast against white diamonds.
There is no universally superior metal. Consider the jewellery you already wear, the colour you prefer, the engagement-ring design, your lifestyle and the wedding ring that may eventually sit alongside it.

Yellow Gold Diamond Ring Styles
Yellow gold works with almost every diamond engagement ring style.
A solitaire diamond ring creates a clean composition where the warm gold band and centre diamond provide the principal contrast.
A solitaire accent diamond ring introduces smaller diamonds into the band, combining yellow gold with additional brilliance.
Halo diamond rings surround the centre stone with smaller diamonds and can create greater visual presence, while trilogy diamond rings use three principal stones as part of the composition.
Yellow gold is also particularly effective in vintage diamond rings, where the warmth of the metal can complement detailed galleries, milgrain-inspired features and more decorative settings.
Yellow Gold with a Platinum Diamond Setting
A yellow gold engagement ring does not necessarily need to be manufactured entirely from yellow gold.
One particularly effective option is a yellow gold band combined with a platinum diamond setting.
This retains the warm appearance of yellow gold around the finger while placing the centre diamond within a naturally white precious metal. The platinum setting can visually blend with the diamond, while the contrast between the white setting and yellow gold band becomes part of the design.
Two-tone construction can also be useful where the visual qualities of yellow gold are desired through the band but the design benefits from different properties around the diamond setting.
Because Polished Diamonds develops rings using CAD, the relationship between the two metals can be incorporated into the design from the beginning rather than treated as an afterthought.
Natural or Lab-Grown Diamonds in Yellow Gold
Yellow gold can be paired with either a certified natural diamond or lab-grown diamond.
Both options can be used with yellow gold and across virtually every popular diamond shape, including round brilliant, oval, emerald, radiant, pear, princess, cushion, marquise and Asscher.
Natural diamonds appeal to clients who value geological origin and rarity, while lab-grown diamonds can provide greater flexibility around diamond size and specifications for a particular budget.
The ring can then be designed around the exact dimensions of the selected diamond rather than requiring the stone to fit a predetermined setting.
Does Yellow Gold Need Rhodium Plating?
No. Yellow gold does not require rhodium plating to create its colour.
The yellow appearance comes from the gold and the composition of the alloy itself.
This is an important difference from white gold, which is commonly rhodium plated to create a bright white surface.
Yellow gold will still develop normal surface marks and wear over time, particularly on an engagement ring worn every day. It can be professionally cleaned, inspected and polished when required, but there is no white surface coating that needs to be renewed to maintain its yellow colour.
Yellow Gold Engagement Rings and Wedding Rings
If your yellow gold engagement ring will eventually sit alongside a wedding ring, considering both rings during the design stage can produce a more cohesive result.
Setting height, band width, profile and the position of the centre diamond all influence how closely a wedding band can sit beside an engagement ring.
CAD allows our designers to consider this relationship before manufacture begins.
A yellow gold wedding ring creates a consistent metal colour across the set, while pairing yellow gold with platinum, white gold or rose gold can create an intentional mixed-metal combination.
Custom Yellow Gold Diamond Rings Made in New Zealand
Through our Design Your Own Diamond Ring service, your yellow gold engagement ring can be created specifically around your chosen diamond, finger size, preferred gold purity and design.
Our jewellery designers use professional three-dimensional CAD to develop and refine the ring before manufacture begins.
This allows us to accurately consider:
- centre-diamond dimensions and position
- claw and setting construction
- band width and depth
- setting height
- accent-diamond placement
- wedding-ring clearance
- precious-metal combinations
- overall proportions and balance
You can review detailed CAD renders of the proposed ring and refine the design before approving it for manufacture.
Once approved, your yellow gold diamond ring is crafted through our dedicated New Zealand jewellery workshop, combining advanced jewellery technology with skilled craftsmanship, diamond setting and hand finishing.
Choose from 9kt, 10kt, 14kt, 18kt or 22kt yellow gold, select a natural or lab-grown diamond, and create a ring designed around your preferences rather than being restricted to a predetermined combination.
