Lab-Grown Diamond Engagement Ring

Sunlight catches the slender silhouette of a marquise diamond, its tapered points tracing a quiet arrow of light across the skin. This semi-set solitaire invites you to choose a center stone that elongates the finger with graceful drama, a shape both bold and intimate.

Crafted in 14K white gold, the mounting balances a delicate profile with sturdy comfort. The slender prongs hold the stone securely while allowing maximum light to enter, enhancing the marquise’s signature brilliance. The band’s smooth finish and moderate width ensure it sits comfortably for everyday wear, whether worn alone or paired with a wedding band.

Each piece is hand-finished in our Williamsburg studio, where precision meets quiet artistry. Our ethical commitment shines through in the lab-grown diamond clarity you select—responsibly sourced, with a smaller environmental footprint.

Ideal for those who appreciate a refined statement, this solitaire suits slender to medium finger sizes and complements a variety of personal styles. Its low-profile setting slips easily under gloves or sleeves, making it a practical choice for daily life.

Should you wish to adjust the fit, resizing is available with care to maintain the band’s seamless curve. Lead times vary slightly depending on stone selection, and we’re happy to guide you through the process.
