Lab-Grown Diamond Engagement Ring

When light catches the elongated silhouette of a marquise diamond, it casts a subtle, graceful sparkle that seems to stretch across the hand like a whispered promise. This semi-set solitaire ring in 10K white gold offers a refined foundation, inviting you to select a center stone that reflects your unique story.

Crafted with a delicate yet secure six-prong setting, the band is polished to a soft sheen that complements the diamond’s sharp facets without overwhelming them. Its low-profile design ensures comfortable daily wear, slipping easily beneath gloves or alongside other stackable bands.

Each piece begins in our Williamsburg studio, where precision meets quiet artistry—every curve and angle inspected to meet exacting standards. The choice of lab-grown diamonds aligns with a commitment to ethical jewelry, reducing environmental impact while delivering exceptional clarity and brilliance.

Ideal for those who appreciate a blend of classic form and modern intention, this mounting suits slender fingers and elongates the hand’s natural lines. The solitaire style emphasizes the marquise’s architectural elegance, making it a striking yet wearable statement.
