Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous shadow across your hand. This semi-set engagement ring invites you to choose a center stone that echoes that graceful, tapered drama.

Crafted in warm 14K yellow gold, the mounting balances delicate strength with a refined silhouette. The solitaire setting is designed with a low profile to sit comfortably beneath daily wear, its polished band smooth to the touch and subtly rounded for a comfort fit. Each curve is hand-finished in our Williamsburg studio, ensuring a seamless union between metal and stone.

Our diamonds are lab-grown, offering a clarity and brilliance born from sustainable practices that respect both earth and artistry.

The ring’s slender band and pointed marquise shape elongate the finger, ideal for those who appreciate a refined statement that layers well with wedding bands or stackable rings. Its modest height makes it glove-friendly and unobtrusive for everyday life.

Should you need resizing, our Brooklyn studio offers precise adjustments to ensure your ring fits as naturally as it feels.
