What Is White Gold?
White gold is yellow gold alloyed with nickel or palladium, then rhodium-plated for its bright white finish. Learn its composition, why it turns yellow, and how it compares to platinum.
White gold is made by mixing yellow gold with white metals — usually nickel, palladium, or silver — to neutralise the yellow colour. Most white gold jewellery is then coated with rhodium, a platinum-group metal, to give it a bright reflective finish. 18K white gold contains 75% pure gold, identical in purity to 18K yellow gold.
Volume visualization — gold vs. white metals
Each droplet = same volume. Because gold is denser, it needs fewer droplets to represent the same weight. White-metal droplets (nickel, palladium) are lighter, so they take up more space.

The white gold recipe
White gold starts as regular yellow gold, then gets mixed with white metals
yellowish
Not a natural element
White gold does not exist in nature. Search the periodic table and you won't find it — it's an alloy created by humans.
The rhodium secret
Even when mixed with white metals, the alloy still looks yellowish. The bright white you see on jewelry comes from a thin rhodium plating on top.
It will turn yellow over time
As you wear it, the rhodium layer gradually wears off — revealing the slightly yellow alloy underneath. A jeweler can re-plate it for a small fee.
Understanding Rhodium Plating
Rhodium plating is what transforms yellowish white gold into the brilliant white metal you see in jewelry stores. This ultra-thin layer — typically only 0.75 to 1.0 microns thick — is what gives white gold its mirror-like finish and protects the underlying alloy.
Why Rhodium?
- •Whitest metal: Rhodium is one of the whitest, most reflective metals on Earth
- •Incredibly hard: 4-5 times harder than gold, provides scratch resistance
- •Hypoallergenic: Won't cause skin reactions like nickel can
- •Tarnish-proof: Doesn't oxidize or corrode with daily wear
How Long It Lasts
- •Rings: 1-2 years (high friction areas wear faster)
- •Pendants/earrings: 3-5 years (less contact, slower wear)
- •Signs of wear: Yellowish tint appearing in worn spots
- •Re-plating cost: Usually $50-$75 at most jewelers
Important: Rhodium is NOT permanent
Many people buy white gold thinking it will stay white forever. In reality, the rhodium plating will wear off with regular use, especially on rings. This is completely normal and expected — it's part of owning white gold jewelry. Budget for periodic re-plating every 1-3 years depending on wear.
Nickel Allergies & White Gold
If you've ever had a rash from cheap jewelry, costume jewelry, or belt buckles, you might have a nickel allergy. This is crucial to know before buying white gold, because many white gold alloys contain nickel as a whitening agent.
The Nickel Problem
About 10-20% of people have nickel allergies. When nickel touches your skin, it can cause redness, itching, rashes, and in severe cases, blisters. The EU has banned nickel in jewelry for this reason.
Nickel-Free Alternatives
Ask your jeweler for palladium white gold instead. Palladium is a naturally white metal that doesn't cause allergies. It costs slightly more, but it's worth it if you're sensitive to nickel.
Rhodium Protection
The good news: rhodium plating creates a protective barrier between your skin and the nickel alloy underneath. But if the plating wears off, the nickel can touch your skin and cause a reaction.
How to Test for Nickel Allergy
- 1. Spot test at home: Place a nickel coin (US 5-cent coin is 75% nickel) against your inner wrist with a bandage for 24 hours. Redness or itching = likely allergy.
- 2. Professional patch test: Visit a dermatologist for a comprehensive allergy test. They'll test for nickel and other common allergens.
- 3. Ask your jeweler: Request the exact alloy composition. Reputable jewelers can provide documentation showing whether their white gold contains nickel.
Caring for Your White Gold Jewelry
White gold requires more maintenance than yellow gold or platinum due to its rhodium plating. Follow these care tips to keep your jewelry looking brilliant for years:
Do These Things
- ✓ Remove before swimming: Chlorine can damage both the rhodium plating and the gold alloy underneath
- ✓ Clean regularly: Use warm water, mild dish soap, and a soft toothbrush weekly to remove oils and dirt
- ✓ Store separately: Keep in individual pouches to prevent scratching from other jewelry
- ✓ Get re-plated: When you notice yellowing, take to a jeweler for rhodium re-plating ($50-75)
- ✓ Professional cleaning: Visit your jeweler twice a year for ultrasonic cleaning and inspection
Avoid These Things
- ✗ Harsh chemicals: Bleach, ammonia, and chlorine will damage rhodium plating and dull the metal
- ✗ Abrasive cleaners: Baking soda, toothpaste, or rough cloths can scratch the plating
- ✗ 24/7 wearing: Remove rings when doing dishes, gardening, or heavy work to reduce friction wear
- ✗ Ignoring yellowing: Once rhodium wears off, the underlying alloy can tarnish faster — re-plate promptly
- ✗ DIY re-plating: Rhodium plating requires professional equipment — don't attempt at home
Quick Cleaning Recipe
You'll need:
- • Warm water (not hot)
- • 2-3 drops mild dish soap
- • Soft toothbrush
- • Lint-free cloth
Steps:
- 1. Mix soap and warm water in a bowl
- 2. Soak jewelry for 10-15 minutes
- 3. Gently brush with soft toothbrush
- 4. Rinse under warm water
- 5. Pat dry with lint-free cloth
