Lab-Grown Diamond Engagement Ring
Sunlight catches the gentle curves of a 6 x 6 mm cushion diamond, its soft corners glowing with a vintage warmth that invites closer admiration. This semi-set engagement ring foundation in 14K yellow gold offers a tactile warmth beneath the finger, shaped and polished in our Williamsburg studio to a smooth comfort fit that wears effortlessly every day.
Each band is hand-finished with subtle accents that frame the center stone’s eventual sparkle, crafted with precision to hold your chosen cushion cut securely in a low-profile setting that balances presence with practicality. The yellow gold’s rich hue deepens over time, a quiet companion to the diamond’s shifting light.
Our diamonds are lab-grown, ensuring clarity and brilliance without the environmental cost of traditional mining. This ethical choice reflects a commitment to sustainability woven into every piece we create.
Designed for those who appreciate artisan detail and understated elegance, this ring suits a range of hand sizes and complements stacking with other bands or wedding rings. Its low profile makes it glove-friendly and ideal for daily wear without catching.
Should you need resizing or prefer a custom finish, our Brooklyn studio offers personalized consultations to ensure the ring fits your lifestyle perfectly.
