Lab-Grown Diamond Engagement Ring

Imagine the subtle drama of a marquise diamond, its elongated silhouette catching light like a shard of dawn. This semi-set halo engagement ring in warm 18K rose gold offers a handcrafted foundation ready to embrace a 12 x 6 mm center stone, designed to amplify the stone’s graceful taper and vintage allure.

Each band is shaped and polished in our Williamsburg studio, where the artisan’s touch ensures a smooth comfort fit that rests lightly against the finger. The halo setting, meticulously crafted with delicate prongs, enhances brilliance while maintaining a low profile for everyday wear. The rose gold’s soft blush complements the marquise’s elegant geometry, creating a harmonious balance between boldness and refinement.

Our lab-grown diamonds provide a clear, sustainable alternative, reflecting a commitment to ethical jewelry without compromise on beauty or brilliance.

This ring suits those who appreciate a statement piece that remains wearable—its slender band and secure setting make it ideal for stacking or pairing with a wedding band. The semi-set design invites personal choice, allowing you to select a center stone that resonates with your story.

Resizing is straightforward and handled with care in-studio, ensuring your ring fits perfectly as your journey unfolds.
