Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends tracing a delicate arc that seems to cradle the hand. This three-stone semi-set engagement ring in 10K yellow gold offers a warm embrace, the slender band polished to a soft glow that complements the diamond’s graceful geometry.

Crafted with precision in Williamsburg, the setting balances elegance and everyday wearability—its low-profile design ensures comfort beneath gloves or alongside stackable bands. Each prong is hand-finished to secure the 6 x 3.5 mm marquise center, inviting you to select side stones that echo your personal story.

Our diamonds are lab-grown, reflecting a commitment to ethical jewelry that honors both clarity and conscience without compromise.

The gentle curve of the yellow gold band suits those who appreciate subtle romance paired with modern craftsmanship, especially flattering on slender fingers or as part of a layered look. Its semi-set nature allows for customization, making it a thoughtful foundation for your unique vision.

Resizing is available to ensure a seamless fit, and our Brooklyn studio welcomes you to explore this design in person or begin your custom journey online.
