Lab-Grown Diamond Engagement Ring

The elongated silhouette of the marquise diamond, measuring 8 by 4 millimeters, creates a striking visual that gently extends the finger’s line with tapered elegance.

This semi-set solitaire ring foundation is crafted from 14K white gold, offering a sleek, low-profile setting designed for everyday wear. The band’s smooth finish and subtle curvature ensure comfort beneath gloves or alongside stackable pieces, while the secure prong setting awaits your choice of center stone.

Each piece reflects our commitment to ethical jewelry, featuring lab-grown diamonds that balance brilliance with sustainability.

Ideal for those who appreciate refined geometry and a ring that integrates seamlessly into daily life, this mounting suits slender to medium finger sizes and complements a variety of personal styles.

Resizing is available to ensure a precise fit, with careful attention to maintaining the ring’s structural integrity and comfort.
