Yellow and white gold offer different colours, but colour is not the same as purity. Two pieces marked 18K contain the same proportion of gold even if their alloy mixtures and surface finishes look different.
What gives gold its colour?
Pure gold is yellow. Jewellery alloys combine it with other metals to change properties such as colour and working characteristics. Yellow-gold recipes often include silver and copper. White-gold alloys may include metals such as palladium or nickel; exact recipes vary.
An 18K alloy contains 75% gold whether it is yellow or white. The remaining alloy ingredients and manufacturing process matter when comparing performance. Ask about the actual alloy if you have a known metal sensitivity.
Compare appearance and upkeep
| Consideration | Yellow gold | White gold |
|---|---|---|
| Appearance | Warm yellow alloy colour | Paler alloy, sometimes with a bright white surface finish |
| Rhodium finish | Not normally needed to create its yellow colour | Often rhodium-plated, but not every alloy or piece is |
| Wear | Can scratch and develop a worn surface | Can scratch; plating, where present, can wear |
| Selection | Compare colour and finish in person | Ask about the underlying alloy and any replating needs |
Neither colour belongs to one skin tone or diamond colour grade. Compare the complete setting in daylight and indoor light. The surrounding metal can affect your impression of a diamond, so use the stone’s documentation as well as its appearance.
Understand rhodium plating
Some white-gold jewellery has a thin rhodium finish that gives a bright white appearance. Where used, that layer can wear with friction and expose the underlying alloy colour. Replating frequency depends on the piece and how it is worn; there is no universal schedule.
White gold and platinum are different materials, not interchangeable names. GIA’s guide to white jewellery metals explains these differences. Ask a jeweller what finish is present before choosing a maintenance treatment.
Choose care for the setting as well as the metal
Clean gently and avoid harsh chemicals. Do not assume ultrasonic cleaning is suitable simply because the metal is gold: stones, treatments, settings and the condition of the piece also matter. Professional polishing removes some material, so it should be considered rather than routine excessive treatment.

Choose from the options offered for your design
Our online customiser offers the metal choices shown on each product page. A catalogue photograph or this editorial comparison does not add a white-gold option where one is not listed.
