Collection: 18K Gold Rings
Solid 18K gold rings (75% gold), made to order — the color is the gold itself, it never fades or peels. Nickel-free. Choose from 3 stones: CZ / Moissanite / Lab-Grown Diamond across our best-loved designs.
Every ring is hallmarked inside the band with our duck logo (18K · 18K M · 18K L) and comes with a warranty card stating karat and actual weight. Production takes 10 business days, one free resize, and lifetime trade-in value — when gold rises, your ring's value rises with it.
Every design can also be made in 9K White Gold, 18K Rose Gold, or 9K Rose Gold — message us for a quote.
