Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated facets of an emerald-cut diamond, casting a serene, glassy glow that feels both architectural and intimate. This semi-set engagement ring invites your choice of a 7 x 5 mm emerald-cut center, framed by four delicate side stones that trace a subtle arc along the band.

Crafted in warm 18K yellow gold, the band’s smooth finish and gentle taper ensure a comfortable fit that rests low against the finger, ideal for everyday wear. The setting’s refined profile balances presence with practicality, allowing light to dance freely across each stone’s step-cut planes.

Each lab-grown diamond is selected for clarity and brilliance, reflecting a commitment to ethical jewelry that honors both beauty and sustainability. The ring’s design suits those who appreciate architectural elegance paired with a romantic narrative, especially flattering on slender fingers where the elongated shape elongates the hand.

Resizing is available to ensure a perfect fit, and the semi-set nature means your chosen center stone will be expertly mounted in-studio, tailored to your vision. Whether layered with a wedding band or worn solo, this design complements a modern, thoughtful lifestyle.
