Lab-Grown Diamond Engagement Ring
Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, dramatic shadow that dances across the hand. This semi-set engagement ring invites you to select a 10 x 5 mm marquise stone, whose tapered points and graceful curves evoke a refined, vintage allure.
Crafted from warm 14K yellow gold, the band is shaped and polished in our Williamsburg studio with artisan precision. Delicate accent settings frame the center stone, designed to enhance its unique profile while maintaining a low-profile comfort fit that wears seamlessly every day.
Each piece reflects our commitment to ethical jewelry: the marquise diamond you choose will be lab-grown, offering clarity and brilliance with a smaller environmental footprint.
The slender band suits hands that appreciate subtle elegance and works beautifully alongside stackable rings or a wedding band. Its low-profile setting ensures ease of wear, even with gloves or daily tasks.
Should you need resizing, our in-house jewelers provide careful adjustments to maintain the ring’s balance and finish without compromising its artisan character.
