White gold and sterling silver look similar but wear very differently. White gold is a gold alloy, harder and more valuable, usually plated with rhodium for its bright white color and replated every couple of years. Sterling is 92.5 percent silver, much cheaper and softer, and it tarnishes unless it is plated or polished.
In a jewelry case the two can be hard to tell apart. Both are bright, cool and white. The difference shows up after a year of wear, and in the price tag, so it is worth knowing what each one is before you choose.

What white gold is
Gold is naturally yellow. White gold is gold mixed with paler metals, such as nickel, palladium or zinc, which bleach the color toward white without hiding it completely. Most white gold therefore has a faint warm tint, and nearly all white gold jewelry is plated with rhodium, a bright white metal of the platinum family, to give it the crisp white finish you see in the case.
That plating is what you maintain. With wear, rhodium thins on the high points and the inside of a ring, and the warmer alloy shows through. Jewelers recommend replating every couple of years, and checking each year for yellowing. Replating is routine and inexpensive, and the gold underneath is not affected.

What sterling silver is
Sterling silver is 92.5 percent silver, with copper added because fine silver is too soft for most jewelry. It is bright and white when polished, but silver reacts with sulfur compounds in the air to form silver sulfide, the dark film called tarnish. Many sterling pieces are rhodium plated to slow that down, which makes them look even more like white gold, and which wears in the same way.
Sterling silver’s composition and tarnish are described in Wikipedia’s sterling silver entry.
Durability
White gold is the harder and more durable of the two. Annealed sterling silver measures about 56 on the Vickers hardness scale; karat gold alloys measure two to three times that. In practice white gold holds stones more securely and keeps its shape and edges longer, which is why it is the usual choice for engagement rings and diamond settings, and sterling rarely is.
Allergies: the nickel question
Nickel is the most common metal allergy, and some white gold alloys contain it. If your skin reacts to jewelry, ask whether a white gold piece is nickel-free (palladium white gold is) or choose yellow gold. Rhodium plating keeps nickel away from the skin while it lasts, which is another reason to keep it maintained.
Price
White gold costs much more than silver because it is gold: a 14K white gold piece is 58.5 percent gold by weight. Sterling silver gives you the white look for a fraction of the price, which makes it a good way to wear bolder pieces or to try a style.
Which should you choose?
Choose white gold for engagement and wedding rings, diamond jewelry, and anything worn daily that you want to keep for decades.
Choose sterling silver for statement pieces, trend pieces and jewelry worn now and then, where a lower price matters more than decades of wear.
If you like the color of white metal but not the upkeep of plating, look at platinum, or at the difference between metals in our guide to 14K gold vs sterling silver.

White gold vs sterling silver FAQ
Is white gold better than sterling silver?
For daily wear and diamond settings, yes: it is harder and more valuable. Sterling is better value for occasional and statement pieces.
Does white gold tarnish?
Very little. What changes is the rhodium plating, which wears thin and lets a warmer tone show through until it is replated.
How often does white gold need replating?
Usually every couple of years, depending on wear. Check it once a year for yellowing.
Can you tell white gold from sterling silver by looking?
Not reliably. Check the stamp: 14K or 585 for white gold, 925 for sterling.
Does white gold contain nickel?
Some alloys do. Palladium white gold is nickel-free. Ask before buying if you have a nickel allergy.
Is sterling silver plated with rhodium?
Often, to slow tarnish. Like white gold plating, it wears with time.
