Lab-Grown Diamond Engagement Ring

Light catches the elongated points of the marquise shape, casting a delicate, tapered glow that seems to stretch the hand with quiet elegance. This semi-set platinum band awaits your choice of a 7 x 3.5 mm marquise diamond, offering a refined silhouette that balances drama with subtlety.

Crafted in platinum for its enduring strength and cool luster, the mounting features a low-profile setting designed to sit comfortably against the finger, ideal for daily wear. The slender prongs cradle the stone securely while allowing maximum light to pass through, enhancing brilliance without excess height.

Each piece reflects our commitment to ethical jewelry, showcasing lab-grown diamonds that combine clarity and conscience in every facet. This ring’s streamlined form suits those who appreciate a graceful statement—whether worn solo or paired with a stack of complementary bands.

Its comfort fit ensures ease beneath gloves or during everyday tasks, making it a thoughtful choice for an active lifestyle. Should you need adjustments, resizing is handled delicately in-studio to preserve the integrity of the setting.
