Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender beam that dances along the curve of your finger. This semi-set engagement ring invites you to choose a 7 x 3.5 mm center stone, its distinctive shape evoking a quiet drama and graceful elongation.

Crafted in warm 14K yellow gold, the five-stone setting balances vintage romance with modern precision. Each side stone is carefully positioned to enhance the marquise’s tapered points, while the low-profile mounting ensures a comfortable fit for everyday wear. The band’s smooth finish and subtle taper allow it to nestle effortlessly alongside other rings or stand alone with quiet confidence.

Our commitment to lab-grown diamonds means your ring carries a clarity and brilliance born from sustainable innovation, reflecting a thoughtful approach to beauty and ethics.

Designed for those who appreciate refined detail and a silhouette that flatters the hand’s natural lines, this ring suits slender to medium finger shapes and pairs well with delicate stacking bands. Its low profile makes it glove-friendly and ideal for a life in motion.

Should you need adjustments, resizing is handled with care to preserve the integrity of the setting and stones.
