Lab-Grown Diamond Engagement Ring

Light catches the elongated points of a marquise diamond, casting a slender, dramatic silhouette across the hand. This three-stone engagement ring balances architectural grace with intimate detail, its 10 x 5 mm marquise center framed by two delicate side stones.

Crafted in cool platinum, the band is polished to a satin finish that feels smooth against the skin, designed with a low-profile setting to sit comfortably beneath gloves or daily wear. Each stone is securely nestled in handcrafted prongs, a testament to the artisan workshop’s precision and care.

Our lab-grown diamonds offer a clarity and brilliance indistinguishable from mined stones, created with a commitment to sustainability and ethical sourcing that quietly honors the earth.

The ring’s slender silhouette suits those who appreciate refined geometry and a statement that elongates the finger. Its three-stone design invites stacking with complementary bands or wearing solo as a distinctive symbol of connection.

Should you need resizing, our in-house experts ensure a seamless adjustment without compromising the ring’s integrity.
