Three Stone
Aria Trinity Marquise
Set with a lab-grown or natural marquise-cut diamond of about 1 carat — we recommend the lab-grown option first as the modern, ethically conscious choice that delivers identical optical brilliance for a fraction of the cost, while the natural diamond remains a beautiful classical alternative for those who value traditional provenance. The Trinity Crescent is a three-stone engagement ring crafted in your choice of 14-karat or 18-karat gold, weighing approximately 2.94 grams in its 18-karat form. Two round brilliant side diamonds totalling 0.216 carats (each 3 mm) flank the elongated marquise center, creating a balanced trio that flatters the finger and catches light from every angle. Finished with a sleek, polished band, this design is equally at home as an engagement ring or an anniversary gift. All center stones are IGI or GIA certified, ethically sourced.
