Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, dramatic sparkle that draws the eye along the finger’s natural line. This semi-set engagement ring invites you to select a center stone measuring 12 by 6 millimeters, a size that balances bold presence with refined elegance.

Crafted from 14K white gold, the mounting features a delicate yet secure solitaire setting designed in our Williamsburg studio. The artisan’s hand shapes each prong to cradle the marquise with precision, while the band’s smooth finish ensures a comfortable fit for daily wear. Its low-profile design slips easily beneath gloves and pairs effortlessly with stacking bands.

Choosing a lab-grown diamond for this ring reflects a commitment to ethical jewelry, reducing environmental impact without compromising brilliance or clarity.

Ideal for someone who appreciates architectural grace and a statement that elongates the hand, this ring suits slender to medium finger shapes and those seeking a distinctive solitaire silhouette. The semi-set format allows you to customize your center stone, making the design uniquely yours.
