Lab-Grown Diamond Engagement Ring
Sunlight catches the elongated silhouette of a marquise diamond, casting a delicate shadow that dances with every movement. This semi-set engagement ring invites you to choose a center stone that embodies both drama and grace, its 12 by 6 mm proportions stretching elegantly across the finger.
Crafted in warm 14K yellow gold or crisp 14K white gold, the mounting balances a slender band with secure prongs designed to cradle the stone low against the hand. The solitaire setting emphasizes the marquise’s signature tapered points, while the smooth finish ensures a comfortable fit for daily wear.
Each ring is made to order in our Williamsburg studio, where lab-grown diamonds are selected for their clarity and brilliance, reflecting a commitment to sustainable, ethical jewelry without compromise.
The low-profile design suits those who appreciate refined understatement, ideal for stacking or wearing solo. Its shape naturally elongates the finger, flattering a variety of hand sizes and styles.
Resizing is available to ensure a precise fit, and our team is happy to guide you through the selection and setting process, whether in person or online.
