Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, casting a slender, graceful shadow that seems to dance with every movement. This semi-set five-stone engagement ring in platinum frames an 8 x 4 mm marquise center, its tapered points echoing a quiet elegance that elongates the finger.

Each stone is carefully nestled in a low-profile setting, designed for everyday wear without sacrificing sparkle. The platinum band is hand-finished to a smooth comfort fit, its cool weight balancing the delicate drama of the marquise shape. Meticulous inspection ensures every facet aligns with precision, reflecting light with architectural clarity.

Crafted with lab-grown diamonds, this ring embodies a commitment to ethical jewelry—minimizing environmental impact while maximizing brilliance.

Ideal for those who appreciate refined geometry and subtle statement, the slim profile pairs effortlessly with stacking bands or stands alone as a singular expression of devotion. Its shape and size suit slender to medium fingers, offering a glove-friendly silhouette that slips on with ease.

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