Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, its pointed ends drawing the eye along the hand’s natural line. This semi-set three-stone ring invites you to select a center stone measuring 12 by 6 millimeters, a shape known for its dramatic, tapered elegance and vintage-inspired allure.

Crafted from cool 14K white gold, the band is shaped with a subtle comfort fit, gently curving to sit close and low against the finger. The artisan finish reveals hand-polished surfaces and precisely sculpted prongs designed to secure your chosen diamond while allowing maximum light to dance through its facets. The three-stone setting balances presence with wearability, ideal for daily life without excess bulk.

Each diamond is lab-grown, offering a clarity and brilliance that honors sustainable practices without compromise. This ethical choice reflects a commitment to responsible sourcing and environmental mindfulness.

Designed for those who appreciate architectural form and refined detail, this ring complements slender to medium finger sizes and layers beautifully with stackable bands or wedding rings. Its low-profile setting ensures it remains glove-friendly and unobtrusive.
