The USA is the world's largest market for lab-grown diamonds, so there's no shortage of places to buy. The best choice depends on what you want: convenience, customization or the lowest price for a specific stone.
National chains
Large jewelry chains, including Signet's Kay, Zales and Jared and brands such as Pandora, sell lab-grown diamond jewelry nationwide. Pros: try on in store, financing, easy returns. Cons: mostly ready-made pieces; less choice of individual stones.
Independent jewelers
Local jewelers often offer custom design with lab-grown centre stones. Pros: personal service, bespoke rings, local repairs. Cons: compare quotes on the same specification.
Online retailers
Pros: enormous choice of certified loose stones with 360° videos and reports. Cons: you rely on photos; check return windows and shipping insurance.
Direct from the manufacturer
Pros: closest to source pricing and exact specifications, ideal for retailers, designers and informed buyers. Cons: you manage more of the process.
