This three-stone setting pairs a 3 ct oval lab grown diamond center with two pear-shaped lab grown accent diamonds to create balanced brilliance and visual length. Prong-set accents and a refined shank frame the center stone and draw the eye to its shape and sparkle.
Yes. This ring qualifies for one complementary resizing within 60 days, and up to one year if the new size falls within Brilliant Earth’s recommended sizing range. Resizing includes free shipping both ways.
Yes. The prong settings securely hold the lab grown center and pear-shaped accent diamonds while the precious metal band provides a sleek, durable finish suitable for daily wear. Periodic professional cleanings help preserve brilliance.
A simple polished precious metal wedding band offers a classic pairing that highlights the three-stone silhouette, while a pavé diamond band adds extra sparkle for a glamorous stack. For a seamless look choose a contoured or curved band that nestles against the setting and matches the ring’s metal.
Yes. Engraving on the inside of the band is available, and a jewelry specialist can confirm character limits and placement during purchase or at a showroom appointment.
