Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it casts a dramatic, tapered sparkle that draws the eye along the finger’s natural line. This three-stone semi-set engagement ring foundation in 18K white gold offers a refined stage for a 12 x 6 mm marquise center stone, framed by two smaller side gems that balance brilliance with architectural grace.

Each band is meticulously crafted in our Williamsburg studio, where the cool sheen of 18K white gold is hand-finished to a smooth, comfort-fit profile that sits low enough for everyday wear yet high enough to showcase the stone’s unique shape. The prong setting is engineered to secure the marquise’s pointed ends while allowing maximum light to animate its facets.

Our commitment to ethical jewelry is reflected in the exclusive use of lab-grown diamonds, offering clarity and sparkle with a significantly reduced environmental footprint.

This design suits those who appreciate a statement piece that remains practical—its low-profile setting slips easily under gloves and stacks well with wedding bands or delicate bracelets. The elongated marquise shape visually lengthens the finger, ideal for hands seeking a slender, elegant silhouette.

Should you wish to adjust the fit, resizing is available with care to maintain the ring’s structural integrity and finish.
