This setting accepts a wide range of center gem shapes including round, princess, cushion, oval, emerald, pear, radiant, asscher, and marquise. Accent gemstones are emerald-shape sapphires and the ring can be set with a natural or lab grown center gem depending on your preference.
Yes. This ring can be resized, and Brilliant Earth offers one complementary resizing within 60 days, or up to one year when the size is within the recommended range, with free shipping both ways.
Yes. This ring features a low profile, a sturdy band depth, a four-prong basket to secure the center gem, and gallery wire for extra support, all of which contribute to strong everyday wearability.
Gently clean this ring at home with warm water, mild soap, and a soft brush to remove everyday oils, and avoid harsh chemicals that can affect the setting finish. For deeper maintenance, take advantage of complimentary professional cleanings at a Brilliant Earth showroom.
Choose a low-profile or contoured wedding band to sit neatly against the three-stone silhouette, or pair it with a simple polished precious metal band to let the sapphire accents stand out. For added sparkle, a half-eternity diamond band or a band with small sapphire accents creates a coordinated, elegant stack.
