Buying guide
In a channel setting, small stones sit side by side between two walls of metal, with no prongs between them. The walls protect the edges of the stones and give the band a smooth surface that is less likely to catch on clothing. Here the channels hold lab-grown diamond accents, which run toward the lab-grown sapphire at the center: a channel set princess cut lab-grown sapphire and lab-grown diamond ring with a clean, structured look.
Every design comes in lab-grown blue, pink or yellow sapphire. A lab-grown sapphire shares the chemistry of a natural sapphire and is 9 on the Mohs scale, hard enough for daily wear. Carat options run from 1 to 9 carats total weight. Gold comes in 10K, 14K or 18K. Prices start under $400 at the smallest size, and most rings cost between about $900 and $1,400 at that size.
Each ring is made for you in 10–15 days. Shipping is free on orders over $500, returns are accepted within 30 days, and one resize is free within 60 days of delivery.
