Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated facets of an emerald-cut diamond, casting a serene, glassy glow that feels both architectural and intimate. This semi-set platinum band awaits your choice of a 6 x 4 mm emerald-shaped center, offering a refined foundation crafted with meticulous artisan care in our Williamsburg studio.

Hand-forged from cool, durable platinum, the band features a low-profile setting designed for everyday wear, balancing strength with subtlety. Each prong is shaped and polished by hand, ensuring a secure cradle that complements the diamond’s linear elegance without overwhelming it.

Our commitment to ethical jewelry is reflected in the lab-grown clarity of your future stone, reducing environmental impact while maintaining exceptional brilliance.

The slender band’s comfort fit and modest height make it ideal for those who appreciate understated sophistication, whether worn solo or stacked alongside other meaningful pieces. Its shape naturally elongates the finger, enhancing grace without bulk.

Should you need resizing, our in-house experts provide precise adjustments to ensure a perfect fit without compromising the ring’s integrity.
