Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, casting a slender beam that seems to stretch across the skin. This semi-set solitaire invites your choice of an 8 x 4 mm lab-grown marquise, its pointed ends lending a graceful drama that elongates the finger with quiet confidence.

Crafted in 18K white gold, the mounting balances a delicate profile with structural integrity, its slender prongs rising gently to cradle the stone while allowing maximum light to animate each facet. The band’s smooth finish and subtle taper ensure a comfortable fit, designed to wear effortlessly every day.

Each diamond is ethically cultivated, reflecting a commitment to sustainability without compromise on clarity or brilliance.

Ideal for those who favor refined elegance with a hint of vintage allure, this setting pairs beautifully with slender stacking bands or stands strikingly alone. Its low-profile design slips easily beneath gloves or sleeves, making it a versatile choice for daily life in Williamsburg and beyond.
