White gold and platinum are both popular choices for jewelry, especially engagement rings and wedding bands, but they differ in several key aspects, including composition, durability, appearance, maintenance, and price. Here's a detailed comparison:
1. Composition
White Gold: White gold is made by alloying yellow gold with metals like palladium, nickel, or silver to give it a white appearance. To achieve its shiny finish, it’s typically plated with rhodium, which enhances its brightness and protects the metal underneath.
Platinum: Platinum is a naturally white metal, and jewelry made from platinum is usually at least 95% pure platinum. Platinum's purity is higher than that of white gold, which is why it is considered a more luxurious metal.
2. Color and Appearance
White Gold: White gold has a brilliant, silvery-white appearance due to the rhodium plating. Over time, the plating can wear off, revealing a yellowish tint underneath, which requires re-plating to maintain its bright color.
Platinum: Platinum naturally retains its white, silvery appearance without needing any plating. It will develop a patina over time, giving it a slightly softer, antique look. Some people appreciate this patina, while others may prefer to have it polished back to its original shine.
3. Durability and Strength
White Gold: White gold is durable but softer than platinum, meaning it can be scratched more easily. However, the rhodium plating provides extra protection, and small scratches can usually be repaired when re-plating.
Platinum: Platinum is more durable and dense than white gold, making it more resistant to scratches and wear. When platinum does scratch, it tends to displace the metal rather than lose it (unlike white gold), which means it doesn’t wear down over time as quickly. Platinum’s durability makes it an excellent choice for holding precious stones securely.
