Lab-Grown Diamond Engagement Ring
Imagine the quiet confidence of a square diamond poised to catch the light with architectural precision. This semi-set engagement ring foundation in 18K yellow gold awaits your choice of a 4.5 x 4.5 mm square center stone, designed to showcase sharp geometry with subtle brilliance.
Crafted with a low-profile setting, the band offers a secure yet unobtrusive frame that sits comfortably for daily wear. The warm glow of 18K yellow gold complements the clean lines of the square shape, while the mounting’s precise angles ensure a balanced fit that resists catching on fabric or gloves.
Each piece is finished by hand in our Williamsburg studio, inspected for smooth edges and a refined polish that enhances both durability and understated elegance. The semi-set design invites customization, allowing you to select a lab-grown diamond that meets your clarity and cut preferences, reflecting our commitment to ethical jewelry.
Ideal for those who appreciate modern geometry and a ring that integrates seamlessly into an active lifestyle, this mounting supports stacking or solo wear without overwhelming the hand’s natural movement. Its streamlined profile makes resizing straightforward, ensuring a tailored fit over time.
