Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, dramatic sparkle that seems to stretch beyond the finger. This semi-set solitaire ring offers a poised foundation in warm 14K yellow gold, crafted with deliberate artisan precision in our Williamsburg studio.

The band’s smooth, gently rounded profile balances the diamond’s pointed elegance, designed for everyday wear with a comfort fit that feels like a second skin. Each curve is hand-finished to a soft sheen, while the secure prong setting awaits your choice of a 10 x 5 mm marquise stone, ensuring the gem’s brilliance is unhindered and the silhouette remains low-profile enough for stacking or glove-friendly ease.

Our commitment to lab-grown diamonds means this ring begins with a stone as ethically sourced as it is visually striking, reflecting a sustainable approach without compromise. The warm yellow gold complements the marquise’s vintage-inspired shape, making it a refined choice for those who appreciate subtle drama and artisanal craft.

Resizing is straightforward, handled carefully in-studio to maintain the band’s seamless finish and comfort. Typical lead times allow for thoughtful customization without rush.
