Lab-Grown Diamond Engagement Ring

Light catches the elongated curve of a marquise diamond, casting a slender, luminous silhouette that seems to stretch beyond the finger. This semi-set solitaire invites you to choose a center stone that balances delicate drama with refined elegance.

Crafted in 14K white gold, the mounting’s slender prongs cradle the marquise shape with precision, allowing maximum light to pass through the stone’s pointed ends. The band’s subtle taper and smooth finish ensure a comfortable, low-profile fit that slips easily beneath gloves or alongside a wedding band.

Each piece is hand-finished in our Williamsburg studio, where expert jewelers inspect every angle to guarantee a seamless setting and enduring wearability. The choice of a lab-grown diamond reflects a commitment to ethical jewelry, reducing environmental impact without compromising brilliance.

This solitaire suits those who appreciate a ring that feels both intimate and striking—ideal for slender fingers or anyone drawn to the vintage-inspired silhouette of the marquise cut. Its streamlined profile makes it an excellent candidate for stacking or daily wear.

Should you wish to adjust the band size, resizing is available with care to maintain the ring’s delicate balance. Typical lead times accommodate custom stone selection and finishing.
