Lab-Grown Diamond Engagement Ring
Imagine the quiet confidence of a sharply defined square diamond poised to catch the light with architectural precision. This semi-set engagement ring foundation in warm 14K rose gold offers a modern-minimal silhouette, designed to highlight a 9 x 9 mm square center stone of your choosing.
The band’s clean lines and subtle accents create a structured frame that balances clarity with understated elegance. Crafted in Williamsburg, the rose gold is hand-finished to a smooth, comfortable fit that sits low on the finger, making it ideal for daily wear without sacrificing presence.
Each piece is thoughtfully designed to pair seamlessly with stacking bands or to stand alone, its geometry elongating the hand with quiet strength. The semi-set style invites you to select a lab-grown diamond that meets your exact vision, ensuring ethical clarity and sustainability without compromise.
Resizing is available to ensure a perfect fit, and the studio’s careful inspection process guarantees a flawless foundation ready for your custom stone. Whether visiting us in Brooklyn or designing online, this ring base offers a refined starting point for a truly personal expression.
