Lab-Grown Diamond Engagement Ring

When sunlight catches the edges of a square diamond, it fractures into a quiet dance of light—precise, deliberate, and endlessly captivating. This five-stone semi-set engagement ring in 18K rose gold frames a 4 x 4 mm square center stone, its clean lines softened by the warm blush of the metal.

Each band is hand-finished in Williamsburg, Brooklyn, with a low-profile setting that rests close to the finger for everyday comfort. The five-stone arrangement balances sparkle and subtlety, allowing the square center to anchor the design while side stones add gentle shimmer. The rose gold’s satin polish enhances the ring’s tactile warmth, inviting touch as much as gaze.

Crafted with lab-grown diamonds, this ring reflects a commitment to ethical jewelry—minimizing environmental impact without compromising brilliance or clarity.

Its slender band and modest height suit those who favor a refined silhouette, perfect for stacking alongside wedding bands or wearing solo with quiet confidence. The square shape’s architectural clarity complements hands of all sizes, offering a modern geometry that feels both structured and intimate.

Should you need resizing, our Brooklyn studio provides expert adjustments to ensure a seamless fit without disrupting the ring’s delicate balance.
