Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender beam that dances like a whispered promise. This semi-set halo ring in 18K rose gold frames a 9 x 4.5 mm marquise center with delicate pavé accents, creating a subtle glow that feels both intimate and radiant.

Crafted with a low-profile halo setting, the band curves gently for a comfort fit that rests lightly against the finger. Each rose gold surface is hand-polished in our Williamsburg studio, ensuring a warm blush tone that complements the diamond’s sharp elegance without overwhelming it.

Our lab-grown diamonds offer the same optical brilliance as mined stones, with a traceable origin and a lighter environmental footprint, reflecting a quiet commitment to ethical jewelry.

The elongated marquise shape naturally elongates the hand, ideal for those who appreciate a refined yet distinctive silhouette. Its halo setting adds dimension without bulk, making it suitable for daily wear and easy to stack with complementary bands.

Should you need a custom fit, resizing is available to ensure the ring feels as effortless as it looks. Typical lead times allow for thoughtful crafting without rush.
