►Metal: Solid rose gold — 10K, 14K, or 18K, selected from the drop-down.
Every ring in this set is crafted in solid rose gold — never plated or gold-filled — in the karat you choose. 10K is the most durable and most affordable option. 14K offers the classic balance of warmth and strength, and it is our default. 18K carries the highest gold content for the richest, deepest color. The warm rose hue is permanent: it won’t fade, wear off, or turn your skin green. Not sure which to pick? Read our 10K vs 14K vs 18K gold karat comparison guide.
