Lab-Grown Diamond Engagement Ring

Light catches the elongated silhouette of the marquise diamond, its pointed ends tracing a delicate arc that seems to stretch the fingers with quiet elegance. This three-stone semi-set ring in 14K white gold offers a graceful foundation for a 7 x 3.5 mm center stone, designed to frame your choice with subtle brilliance.

Crafted in Williamsburg, the band’s smooth, low-profile shank ensures comfortable daily wear while the prong setting balances security with maximum light exposure. Each curve is hand-finished and inspected to meet exacting standards, reflecting the studio’s commitment to refined craftsmanship.

Choosing a lab-grown diamond here means embracing clarity and sustainability without compromise—ethical jewelry that honors both beauty and conscience.

The slender silhouette suits hands that appreciate a refined statement, pairing effortlessly with stacking bands or worn solo for a distinctive yet understated look. Its low profile fits comfortably beneath gloves or sleeves, making it a versatile companion for everyday moments.

Resizing is available to ensure a perfect fit, with lead times tailored to your custom design journey.
