Lab-Grown Diamond Engagement Ring

Sunlight catches the gently curved edges of a 4.1 mm round diamond, poised to become the heart of a story yet to unfold. This semi-set solitaire ring invites your choice of a brilliant center stone, framed by a slender 14K white gold band that melts seamlessly into a warm rose gold interior, offering a subtle contrast felt more than seen.

Crafted in Williamsburg, the band’s low-profile setting ensures a comfortable fit for everyday wear, its smooth finish refined by hand and inspected meticulously to balance durability with elegance. The solitaire style highlights the diamond’s classic round cut—renowned for its lively sparkle and timeless appeal—ready to amplify the light of your chosen gem.

Each lab-grown diamond option reflects a commitment to ethical sourcing and sustainability, embodying a modern approach to fine jewelry without compromise. The ring’s slender silhouette suits those who favor understated grace, ideal for stacking alongside wedding bands or wearing solo with quiet confidence.

Should you need resizing, our Brooklyn studio offers personalized adjustments to ensure a perfect fit without disrupting the ring’s delicate proportions. Lead times vary depending on stone selection but are communicated clearly during the design process.
