Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate shadow that dances with every movement. This semi-set solitaire invites you to select a center stone that echoes your personal story, framed by an 18K yellow gold band that warms the skin with subtle radiance.

Crafted in Williamsburg, Brooklyn, the band’s slender profile and smooth finish ensure a comfortable fit for daily wear, while the low-set mounting keeps the diamond close to the hand, blending elegance with practicality. The solitaire setting’s minimal design highlights the marquise’s tapered points and brilliant facets, emphasizing its graceful drama without distraction.

Each lab-grown diamond chosen for this ring reflects a commitment to ethical jewelry, offering clarity and fire without the environmental cost of traditional mining. The warm yellow gold complements the stone’s fiery sparkle, creating a harmonious balance between metal and gem.

Ideal for those who appreciate refined understatement and a ring that layers effortlessly with other bands or stands alone with quiet confidence. Its slender shape suits a variety of finger sizes, elongating the hand with a subtle architectural grace.

Should you wish to adjust the band size, resizing is handled with care in-studio to maintain the ring’s seamless silhouette. Typical lead times allow for thoughtful customization without rush.
