Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise, casting a slender, graceful shadow across the hand. This three-stone semi-set engagement ring features an 8 x 4 mm marquise center, poised to frame your chosen diamond with delicate side stones that enhance its tapered drama.

Crafted from warm 14K yellow gold, the band is shaped in a refined comfort fit that feels natural for daily wear. The artisan hands of our Williamsburg studio carefully form and polish each curve, ensuring a low-profile setting that slips easily beneath gloves or alongside stackable bands. The prongs are precisely finished to cradle your center stone securely while allowing light to flood its facets.

Our commitment to ethical jewelry shines through with lab-grown diamonds, offering clarity and brilliance without compromise. This choice supports sustainability while honoring the timeless allure of fine gems.

Designed for those who appreciate architectural elegance with a touch of vintage flair, the marquise shape elongates the finger and pairs beautifully with slender side stones. Whether your style leans toward minimalist or statement, this ring adapts effortlessly.

Should you need resizing or prefer a custom side stone selection, our Brooklyn studio welcomes your questions with thoughtful guidance and expert care.
