Lab-Grown Diamond Engagement Ring

Sunlight catches the sharp edges of a 9 x 9 mm square diamond, casting a precise, architectural glow that feels both bold and intimate. This five-stone semi-set engagement ring foundation invites your choice of center gem, framed by a delicate balance of side stones that echo its geometric clarity.

Crafted in warm 18K yellow gold, the band’s smooth finish contrasts gently with the cool gleam of white gold prongs, creating a subtle interplay of tones that enhances the ring’s refined structure. The low-profile setting ensures the ring sits comfortably for daily wear, while the careful hand-polishing reveals a tactile softness beneath its crisp lines.

Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that offer exceptional clarity and brilliance with a lighter environmental footprint.

Designed for those who appreciate modern geometry with a romantic edge, this ring suits hands that favor architectural shapes and a confident, yet understated statement. Its five-stone layout pairs beautifully with stacking bands or worn solo, and the semi-set style allows you to select a center stone that resonates with your personal story.
