Lab-Grown Diamond Engagement Ring

Sunlight catches the marquise diamond’s elongated silhouette, casting a delicate dance of light that traces the curve of your hand. This halo setting cradles a 10 x 5 mm lab-grown marquise, its pointed ends softened by a ring of shimmering pavé that amplifies every facet’s fire.

Crafted in cool platinum, the band offers a subtle weight and a smooth comfort fit, designed for daily wear without intrusion. The low-profile halo setting keeps the silhouette elegant and glove-friendly, while expert hand finishing ensures each prong secures the stone with precision and grace.

Our diamonds are grown in controlled environments, reflecting a commitment to ethical jewelry that honors both clarity and conscience.

Ideal for those who appreciate a blend of vintage-inspired romance and modern craftsmanship, this ring complements slender fingers and pairs beautifully with stackable bands or a wedding band of your choice.

Should you need a custom size, resizing is available to ensure a perfect fit without compromising the ring’s delicate balance.
