Choose your gold: 10K, 14K, or 18K solid yellow gold
Every ring in this set is made to order in your choice of karat, selected from the drop-down:
► 10K — the most durable and most affordable option, with a slightly lighter gold tone
► 14K — the classic balance of durability and richness, and our most popular choice
► 18K — the highest gold content, for the deepest, warmest yellow color
The warm yellow color is permanent — it will never fade, wear off, or turn your skin green, because the whole piece is solid gold through and through. Not sure which karat is right for you?

Frequently Asked Questions
Which metal should I choose?
All three karats — 10K, 14K, and 18K solid yellow gold — are beautiful and hard-wearing. 10K is the most affordable and the most scratch-resistant, 14K is our best-selling balance of value and rich color, and 18K has the highest gold content for the warmest, deepest yellow. You can compare them side by side in our 10K vs 14K vs 18K gold karat comparison guide.
Is this real solid gold?
Yes. This ring set is crafted from solid gold in your chosen karat — 10K, 14K, or 18K — never gold-plated or gold-filled.
