Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curves of an oval diamond, casting a gentle glow that seems to stretch across the hand like a whispered promise. This semi-set engagement ring invites you to choose a 9 x 7 mm oval center stone, known for its graceful elongation that visually lengthens fingers with quiet elegance.

Crafted in cool, enduring platinum, the split shank design frames the center with delicate accent stones, offering a subtle interplay of light and shadow. The band’s low-profile setting ensures a comfortable fit for daily wear, while the smooth finish reflects the meticulous hand-polishing and rigorous inspection each piece undergoes in our Williamsburg studio.

Our commitment to lab-grown diamonds means this ring carries a clarity and brilliance born from sustainable practices, aligning beauty with conscience.

Ideal for those who appreciate a refined silhouette that balances statement with subtlety, this ring pairs effortlessly with stacking bands or stands alone as a singular expression of devotion. Its design accommodates resizing and gentle care, making it a lifelong companion.
