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 foundation in warm 18K yellow gold awaits your choice of an 8 x 4 mm marquise center stone, ready to become a singular expression of your story.

Handcrafted in our Williamsburg studio, the band is shaped for comfort with a subtle taper that balances the diamond’s pointed elegance. The low-profile prong setting is designed to secure the stone while allowing maximum light to enter, enhancing brilliance without excess height. Each ring undergoes meticulous finishing and inspection to ensure smooth edges and a flawless polish that feels as refined as it looks.

Our commitment to ethical jewelry is reflected in the option to pair this mounting with a lab-grown diamond, offering clarity and sparkle with a reduced environmental footprint.

Ideal for those who appreciate a bold yet graceful silhouette, this solitaire mounting suits slender to medium finger sizes and pairs beautifully with stacking bands or a wedding ring. Its streamlined profile makes it glove-friendly and comfortable for daily wear.

Should you need resizing or prefer a custom adjustment, our Brooklyn studio offers personalized consultations to ensure the perfect fit and finish.
