Platinum Marquise Engagement Ring
Platinum Marquise Engagement Ring
A bold fusion of modern geometry and timeless elegance, this custom-designed platinum engagement ring is built around a striking marquise center stone. The architectural setting features 10 round brilliant diamonds with an additional diamond accent on the side, creating a clean, geometric silhouette that's unlike anything you'll find in a traditional jewelry case.
Every detail of this ring is fully customizable — from the center stone you choose to the finishing touches that make it uniquely yours. The center stone is not included, giving you complete freedom to select the shape, size, and quality that fits your vision and budget, whether that's a lab-grown or natural marquise diamond or gemstone.
Crafted at Farsi Jewelers in Sandy Springs, GA — where custom design is our specialty since 1998.
