Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous shadow across your hand. This semi-set engagement ring invites you to choose a 10 x 5 mm center stone that balances dramatic presence with refined elegance.

Crafted from warm 18K yellow gold, the five-stone setting embraces the center with gently curved prongs, allowing light to flood the facets from every angle. The band’s subtle taper and polished finish offer a comfortable fit that feels natural for daily wear, while the low-profile design slips easily beneath gloves or alongside other rings.

Each lab-grown diamond is selected for clarity and brilliance, reflecting a commitment to sustainable luxury without compromise. The elongated marquise shape lends a graceful, almost poetic line that visually lengthens the finger, perfect for those who appreciate a blend of classic form and modern artistry.

Designed for those who cherish meaningful detail, this ring pairs beautifully with delicate stacking bands or stands alone as a statement of quiet confidence. Resizing is available to ensure a tailored fit, with careful hand finishing in our Williamsburg studio.
