Platinum is naturally white, denser, hypoallergenic and holds stones very securely, but it costs more and develops a soft, matte patina over time. White gold looks just as bright when new because it is plated with rhodium, costs less and is lighter, but it needs re-plating every year or two to stay bright white. Choose platinum for a low-maintenance heirloom ring; choose white gold for the look at a lower price.
White gold and platinum look almost identical in a new ring. The differences show up in how they wear, how much care they need and what they cost.
Side by side
| White gold | Platinum | |
|---|---|---|
| Color | Bright white from rhodium plating | Naturally white-gray |
| Purity | 58.3% (14k) or 75% (18k) gold | Usually 90 to 95% platinum |
| Maintenance | Re-plating every 1 to 2 years | Polishing if you want the shine back |
| Wear | Metal is lost when scratched | Metal is displaced, forming a patina |
| Weight | Lighter | Noticeably heavier |
| Allergies | Some alloys contain nickel | Hypoallergenic |
| Price | Lower | Higher |
Color and maintenance
White gold is gold mixed with white metals, then plated with rhodium for a bright, mirror-white finish. The plating wears, especially on the underside of rings, and needs redoing every year or two. It is a quick, inexpensive job at most jewelers.
Platinum is white all the way through and never needs plating. Over time it develops a soft, satin patina that many people like; a jeweler can polish it back to a high shine.
Durability
Platinum is dense and tough. When scratched, the metal moves rather than wearing away, which makes it very secure for holding stones in prongs. White gold, especially 14k, is hard and scratch-resistant, but metal is gradually lost as it wears. Both last for decades with normal care.
Comfort and weight
Platinum is much denser, so a platinum ring feels heavier. Some people like the substantial feel; others prefer lighter white gold.
Price
Platinum rings usually cost more, partly because more metal goes into the same ring and partly because it is harder to work. White gold gives you the same look for less.
Which to choose
- Low maintenance, heirloom feel, sensitive skin: platinum.
- Best value, lighter feel, brightest white when new: white gold.
- Pairing with an existing ring: match metals so the two wear the same way.
Common questions
Does white gold turn yellow?
As its rhodium plating wears, white gold can show a faint warm tint from the gold underneath. A jeweler can re-plate it to restore the bright white finish.
Is platinum worth the extra cost?
For a ring you wear every day for decades, many people find it worth it: it is naturally white, very secure for prongs, and doesn't need plating. If budget matters more, white gold gives the same look for less.
Which is better for sensitive skin?
Platinum. It is usually 90 to 95% pure and hypoallergenic. Some white gold alloys contain nickel, so look for nickel-free white gold if you have a nickel allergy.
