Buying guide
The side stones set the mood of a round diamond engagement ring with side stones. Round side stones match the center for a classic three stone look. Pear and marquise side stones add length and point toward the center. Baguettes and trapezoids give a crisp, step-cut line, and trillions add a sharp triangular edge. A few designs use bar or bezel settings for the sides, which sit lower and protect the edges.
Gold comes in 10K, 14K or 18K. Platinum suits detailed settings that need strong prongs, and silver keeps the cost lowest. Band widths mostly run about 1.8 to 2.5 mm. Many designs can also be ordered for a fancy yellow, green, blue or pink center. Settings start under $250, and most are between about $880 and $1,400. That price covers the setting; the 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.
Round side stones are the safest match for a round diamond, since they share its shape and brilliance. Pear and marquise side stones add length and point toward the center, while baguettes or trapezoids give a clean step-cut contrast. In this collection, matched round sides in a three stone layout are the most common, and the side stones are lab-grown diamond accents set to frame the center you choose.
