Lab-Grown Diamond Engagement Ring

Sunlight catches the gentle curve of an 8 mm round diamond, its facets unfolding like whispered promises. This semi-set solitaire invites you to choose a center stone that will become the quiet heartbeat of your story.

Crafted in 18K white gold, the mounting’s slender band balances strength with subtlety, designed to sit low against the finger for everyday grace. The polished finish reflects soft glimmers, while the prong setting secures the stone with delicate precision, allowing light to dance freely through each facet.

Our diamonds are lab-grown, offering a clarity and brilliance born from sustainable innovation, a mindful choice for those who value both beauty and ethics.

The ring’s low-profile silhouette suits hands that favor understated elegance, and its comfort fit ensures it wears seamlessly alongside wedding bands or stackable rings. Its adaptable design welcomes a variety of round diamond sizes, making it a versatile foundation for your custom vision.

Should you need resizing, our Brooklyn studio provides attentive adjustments to ensure a perfect fit without compromising the ring’s refined lines.
