Lab-Grown Diamond Engagement Ring
When light catches the gentle curves of a 9 x 9 mm heart-shaped diamond, it reveals a quiet declaration of love—bold yet intimate. This semi-set engagement ring foundation in warm 14K rose gold offers a modern-minimal silhouette, designed to frame your chosen center stone with clarity and structural confidence.
Crafted in Williamsburg, the band’s smooth finish and subtle accents emphasize a refined geometry, while maintaining a comfortable, low-profile fit ideal for everyday wear. Each piece undergoes meticulous hand inspection to ensure precision and durability.
Our commitment to ethical jewelry shines through the exclusive use of lab-grown diamonds, combining sustainability with exceptional clarity and brilliance.
The slender rose gold band suits those who appreciate a contemporary aesthetic with a touch of softness, pairing effortlessly with stacking rings or standing alone as a statement of personal style.
Should you need resizing or prefer a custom accent arrangement, our Brooklyn studio offers a collaborative, pressure-free design experience tailored to your vision.
