Lab-Grown Diamond Engagement Ring

Sunlight catches the soft, rounded corners of a 7 x 7 mm cushion diamond, its gentle glow poised between vintage warmth and modern clarity. This three-stone semi-set ring features a 14K yellow gold band, hand-shaped and polished in our Williamsburg studio to a smooth, comfortable fit that rests lightly on the finger.

The setting’s artisan craftsmanship reveals itself in subtle details: secure prongs cradle the center stone while side diamonds frame it with quiet brilliance, all designed for everyday wear without excess height. Each curve and angle is refined through meticulous finishing and inspection, ensuring the ring’s balance and durability.

Our commitment to lab-grown diamonds means this piece carries a clarity and ethical transparency that honors both the earth and your values.

Its low-profile silhouette suits those who appreciate a classic shape with a contemporary edge—ideal for stacking with wedding bands or worn solo as a statement of enduring style. The 14K yellow gold band offers warmth against the skin, complementing a variety of complexions and personal styles.

Should you need resizing, our Brooklyn studio handles adjustments with care, preserving the ring’s integrity and finish.
