Lab-Grown Diamond Engagement Ring
Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous shadow that dances across the skin. This semi-set engagement ring invites you to select a 10 x 5 mm marquise stone, whose tapered points and graceful curves evoke a quiet drama and elongate the finger with subtle elegance.
Crafted from 10K white gold, the band is shaped in our Williamsburg studio with a delicate artisan touch—its smooth finish and slender profile designed for everyday wear. The accent settings frame the center stone with precision, offering a refined balance between sparkle and comfort without overwhelming the hand.
Each piece reflects our commitment to ethical jewelry: the marquise diamond you choose will be lab-grown, ensuring clarity and brilliance with a lighter environmental footprint. This ring’s low-profile setting and slender shank make it ideal for those who prefer a glove-friendly, stackable band that moves seamlessly with daily life.
Should you need a custom fit, resizing is available to ensure the ring feels as natural as it looks. Our process is collaborative and pressure-free, whether you visit our Williamsburg studio or design with us online.
