10K Gold — Real Solid Gold, the Lowest Karat You Can Buy

10K gold is 41.7% pure gold by weight — 10 parts gold out of 24 — alloyed with stronger base metals like copper, silver, and zinc. It is the lowest karat that may legally be sold as “gold” in the United States, and every ring in this collection is solid 10K gold all the way through, not gold-filled or gold-plated. Because it carries the highest percentage of alloy of the three common ring karats, 10K is also the hardest and the most scratch-resistant, and it is the most affordable solid-gold option we carry.

If you want more gold content and a richer color at a higher price point, see our 14K gold rings. 10K comes in yellow, white, and rose gold — white gold pieces are rhodium-plated for a bright, cool finish; see what is white gold for how that finish works and what upkeep it needs.

When 10K Is the Right Choice

10K gold’s extra hardness makes it a practical choice for daily wear and active hands — a ring that gets knocked against desks, tools, and doorframes holds up better in 10K than in a softer, higher-karat gold. It’s also a common first-ring choice, since a lower gold content brings the metal cost down without giving up solid, legally-marked gold.

For a diamond or gemstone ring on a set budget, 10K is one way to put more of that budget toward the stone rather than the metal. Browse the full ring collection across every karat and style, or see our selection of diamonds and gemstones to pair with a 10K setting.
