Lab-Grown Diamond Engagement Ring

Light catches the elongated points of the marquise shape, casting a subtle, tapered brilliance that draws the eye along the finger’s natural line. This semi-set three-stone engagement ring in platinum offers a refined foundation, ready to showcase an 8 x 4 mm marquise center stone with architectural poise.

Crafted in platinum for enduring strength, the mounting features a low-profile design that sits close to the hand, balancing elegance with everyday comfort. The three-stone setting is engineered for secure wear, with precise prongs that hold each gem firmly while allowing maximum light to enhance sparkle. The smooth band’s weight and contour ensure a comfortable fit, ideal for daily wear and layering with other bands.

Each lab-grown diamond chosen for this ring reflects a commitment to sustainable sourcing, offering clarity and fire without compromise. The ethical choice aligns with a modern approach to fine jewelry, mindful of environmental impact.

Designed for those who appreciate subtle drama and clean lines, this ring complements slender to medium finger shapes, elongating the hand with its marquise silhouette. Its low profile makes it glove-friendly and unobtrusive for active lifestyles.
