Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous shadow that hints at quiet elegance. This semi-set solitaire invites you to select a 5 x 3 mm center stone that will stretch gracefully along the finger, its pointed ends drawing the eye with subtle drama.

Crafted in warm 14K rose gold, the mounting features delicate prongs that cradle the stone with precision, allowing maximum light to enter and amplify the diamond’s natural brilliance. The band’s gentle curve and polished finish ensure a comfortable fit for everyday wear, while the low-profile setting keeps the ring close to the hand, ideal for stacking or pairing with a wedding band.

Each piece is meticulously finished in our Williamsburg studio, where expert jewelers inspect every detail to balance durability with refined craftsmanship. The rose gold’s soft blush tone complements the marquise’s vintage-inspired shape, creating a harmonious blend of modern design and romantic heritage.

Our commitment to sustainability is reflected in the use of lab-grown diamonds, offering clarity and sparkle with a lighter environmental footprint. This ring suits those who appreciate a distinctive silhouette that elongates the finger and carries a quiet confidence without excess.

Should you wish to adjust the band size, resizing is available to ensure a seamless fit. The semi-set design allows you to choose a center stone that resonates personally, making the ring uniquely yours.
