Lab-Grown Diamond Engagement Ring
Light catches the elongated silhouette of the marquise diamond, its pointed ends drawing the eye along a graceful arc. This semi-set engagement ring foundation in 14K yellow gold is crafted to showcase an 8 x 4 mm marquise center stone of your choosing, framed by delicate accent settings that enhance its sculptural form.
The band is designed with a low-profile setting that sits close to the finger, offering both comfort and security for everyday wear. Each curve and prong is meticulously finished in our Williamsburg studio, ensuring a smooth feel beneath the hand and a refined balance between presence and subtlety.
Our commitment to sustainability is reflected in the lab-grown diamond clarity this mounting invites—ethical jewelry that honors both beauty and responsibility.
Ideal for those who appreciate a sleek silhouette and a ring that layers effortlessly with other bands, this mounting complements a variety of hand shapes and sizes without overwhelming. Its streamlined design is glove-friendly and built for daily life.
Should you need resizing or customization, our Brooklyn studio offers expert adjustments with care and precision, typically completed within a few weeks.
