Lab-Grown Diamond Engagement Ring
Sunlight catches the soft, rounded corners of a 12 x 12 mm cushion diamond, its gentle glow inviting quiet admiration. This semi-set engagement ring foundation in 10K yellow gold offers a warm, classic backdrop for a stone that balances vintage charm with modern presence.
Crafted with a low-profile bezel setting in mind, the band’s smooth contour ensures comfort for everyday wear while minimizing snagging. The yellow gold’s subtle sheen is hand-finished in our Williamsburg studio, where each curve is polished to a refined glow and inspected for seamless fit.
Choosing a lab-grown diamond here means embracing clarity and brilliance without compromise, reflecting a commitment to ethical jewelry that respects both earth and artisan.
Designed for those who appreciate a substantial yet wearable statement, this mounting suits a larger cushion cut that elongates the finger with its soft, pillow-like shape. Its modest height and secure setting make it ideal for stacking with wedding bands or wearing solo with ease.
Should you need resizing or prefer a custom accent arrangement, our Brooklyn studio offers personalized consultations to ensure your ring fits perfectly and reflects your vision.
