Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its tapered points drawing the eye along the finger with quiet drama. This semi-set engagement ring foundation in 10K yellow gold awaits your choice of a 9 x 4.5 mm center stone, ready to frame the distinctive shape that elongates and flatters the hand.

Handcrafted in our Williamsburg studio, the band is shaped for comfort and daily wear, with delicate accent settings that enhance the marquise’s unique geometry without overwhelming its refined profile. The warm glow of yellow gold complements the stone’s brilliance, while the low-profile mounting ensures ease beneath gloves or alongside stackable bands.

Each piece is meticulously finished and inspected, reflecting our commitment to artisan quality and subtle sophistication. The lab-grown diamond option offers a clear, sustainable alternative without compromise on clarity or light performance.

Designed for those who appreciate a blend of architectural elegance and understated craftsmanship, this ring suits slender to medium finger sizes and pairs beautifully with complementary wedding bands or personal stackables.

Resizing is available to ensure a precise fit, and our studio welcomes you to explore custom design options in person or online, where your vision shapes every detail.
