My Wife Loved the Ring! 😍

My wife & I have been married for a couple of years but I didn't get her an engagement ring until recently. During a photo shoot we booked, I surprised her with an engagement ring from Brilliant Earth & she loved it! I was initially nervous because I didn't know if she would like the style & diamond size but she and her friends couldn't stop talking about it. The style is elegant, the diamond is remarkable, and the fit is perfect. We couldn't be happier! #sweepstakes ...Read More

Yes. This ring is eligible for one complimentary resizing within 60 days of delivery, or up to one year if the size falls within the recommended sizing range. Outside the complimentary period, resizing is available for a fee and includes free shipping both ways for covered resizing.
Yes. This ring’s cathedral archways provide extra support for the lofted four-prong center stone, and the French pavé accent diamonds are securely pavé set for regular wear. The low profile design also helps create a comfortable, snag-resistant fit.
This ring can be set with a wide range of center stone shapes, including round, princess, cushion, oval, emerald, pear, radiant, asscher, marquise, and heart. The accent diamonds will match the chosen center stone type, and customers may select a natural or lab-grown center gem.
This ring is offered in precious metal options, shown here in 18K white gold with a high-polish finish and rhodium plating. The design also features a mixed-metal detail at the prong setting to accentuate the center gem.
A contoured or curved wedding band will nestle against this ring for a seamless look, and a slim pavé diamond band will echo the French pavé accents for a cohesive stack. For a cleaner aesthetic, a classic polished band complements the cathedral silhouette.
