Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate shadow that dances with every movement. This semi-set engagement ring invites you to choose a 10 x 5 mm marquise center stone, whose tapered points lend a graceful drama and subtly elongate the finger.

Crafted from warm 18K yellow gold, the slender band is designed with a low-profile solitaire setting that embraces the diamond securely while maintaining an elegant, unobtrusive presence. The smooth finish and gentle curvature ensure a comfort fit that feels natural for daily wear, whether worn alone or stacked with complementary bands.

Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that offer clarity and brilliance with a lighter environmental footprint. This choice honors both beauty and responsibility without compromise.

Ideal for those drawn to refined silhouettes and romantic understatement, this ring suits hands that appreciate a balance of bold shape and subtlety. Its semi-set form allows you to select a stone that resonates personally, making the design uniquely yours.
