Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of an oval diamond, its elongated silhouette casting a subtle glow across the hand. This semi-set three-stone engagement ring invites you to select a 7 x 5 mm center stone, poised to harmonize with two delicate side gems that frame it with quiet elegance.

Crafted in cool platinum, the band is shaped for everyday grace—smooth beneath the finger with a low-profile setting that slips comfortably under gloves or rings stacked alongside. Each curve and prong is meticulously finished in our Williamsburg studio, where artisan hands refine every detail to a soft, tactile perfection.

Choosing a lab-grown diamond here means embracing clarity and brilliance without compromise, reflecting a commitment to sustainability that quietly honors the earth.

This design suits those who appreciate refined geometry and a ring that balances presence with subtlety—ideal for slender fingers or anyone seeking a piece that layers effortlessly with other bands.

Should you need resizing or wish to explore stone options, our studio offers personalized guidance to ensure your ring fits both your hand and your vision.
