Lab-Grown Diamond Engagement Ring

The elongated silhouette of the marquise diamond catches the eye with its tapered points and graceful curve, evoking a sense of refined drama. This semi-set solitaire ring in warm 14K rose gold offers a delicate foundation, crafted with hand-finished edges and a low-profile bezel ready to cradle an 8 x 4 mm center stone.

Each band is shaped and polished in our Williamsburg studio, ensuring a smooth comfort fit that rests lightly against the finger. The subtle warmth of rose gold complements the marquise’s vintage-inspired shape, while the semi-set design invites you to select a lab-grown diamond that reflects your personal story.

Our commitment to ethical jewelry shines through the use of sustainably created lab-grown diamonds, reducing environmental impact without compromising brilliance or clarity.

Ideal for those who appreciate artisan craftsmanship and a ring that layers effortlessly with wedding bands or everyday stackables, this setting balances presence with wearability. Its low profile makes it glove-friendly and suited for daily life.

Should you need resizing or prefer a custom finish, our Brooklyn studio offers personalized consultations to ensure your ring fits perfectly.
