Lab-Grown Diamond Engagement Ring

Under the soft glow of Williamsburg’s evening light, the elongated silhouette of a marquise diamond begins to captivate—its tapered points drawing the eye along the hand’s natural lines. This semi-set halo engagement ring offers a delicate frame for an 8 x 4 mm marquise stone, ready to be chosen and set with precision.

Crafted from 14K white gold, the band is shaped and polished in our Brooklyn studio to a smooth comfort fit, ensuring it rests lightly without catching. The halo setting, designed with artisan care, surrounds the center stone with a whisper of smaller diamonds, enhancing brilliance while maintaining a low profile for everyday wear.

Each piece reflects our commitment to ethical jewelry: the marquise diamond is lab-grown, offering clarity and sparkle with a reduced environmental footprint.

Ideal for those who appreciate a refined yet distinctive look, this ring complements slender fingers and pairs beautifully with stackable bands or a wedding band of your choice. Its subtle height and secure setting make it glove-friendly and suitable for daily life.

Should you need resizing or have questions about lead times, our team provides attentive guidance to ensure your ring fits perfectly and arrives on schedule.
