Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous beam across the hand. This semi-set engagement ring invites you to select a 9 x 4.5 mm marquise stone, whose tapered points and graceful curves evoke a refined drama.

Crafted from warm 10K yellow gold, the band is shaped with subtle tapering to complement the diamond’s length. The artisan’s touch is evident in the low-profile prong setting, designed to cradle the stone securely while allowing light to flood its facets. A smooth comfort fit ensures the ring rests naturally, ideal for daily wear without catching or discomfort.

Each lab-grown diamond option reflects a commitment to ethical sourcing and environmental mindfulness, offering clarity and brilliance without compromise.

This solitaire silhouette suits those who appreciate architectural elegance with a vintage whisper. Its slender profile pairs beautifully with stacking bands or stands strikingly alone. The semi-set foundation allows for personalized stone selection, making it a truly bespoke expression.

Resizing is straightforward, handled with care in our Williamsburg studio to maintain the ring’s balance and finish.
