Lab-Grown Diamond Engagement Ring

Sunlight catches the sharp edges of a 10mm square diamond, its facets whispering quiet brilliance beneath a delicate halo. This semi-set engagement ring invites you to select a center stone that balances bold geometry with intimate sparkle.

Crafted in warm 10K rose gold, the band curves gently for a comfort fit, its low-profile halo setting designed to sit close to the finger—ideal for daily wear without catching. Each piece is hand-finished in our Williamsburg studio, where precision meets subtle artistry in every detail.

Our lab-grown diamonds offer clarity and fire with a lighter environmental footprint, reflecting a commitment to ethical jewelry without compromise. The square shape lends architectural strength and modern elegance, perfect for those drawn to clean lines with a romantic edge.

Designed to complement a variety of hand sizes, this ring’s halo enhances the center stone’s presence while maintaining a refined silhouette that layers beautifully with wedding bands or stackable rings. Its smooth band and modest height ensure it remains glove-friendly and comfortable through every season.

Should you need resizing or wish to explore center stone options, our Brooklyn studio offers personalized consultations with thoughtful timelines tailored to your design journey.
