Buying guide
In a channel setting, small stones sit side by side in a groove cut into the band, held by the metal walls on each side instead of by prongs. Nothing sticks up to catch on sweaters or gloves, and the accents are well protected from knocks. That makes a channel set ring a practical choice for daily wear, with a clean line of sparkle that leads the eye to the blue center.
Gold comes in 10K, 14K or 18K. White gold and platinum make a blue center look cooler and deeper, while yellow and rose gold add warmth. Settings start under $350, and most are between about $1,100 and $1,500. That price covers the setting only; the blue center is priced when you choose it.
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.
