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 hand with tapered elegance. This semi-set engagement ring foundation in warm 18K rose gold offers a subtle glow beneath the stone, designed to sit low and close for everyday comfort without sacrificing presence.

Crafted with precision, the band’s smooth finish and secure prong setting ensure the center stone will be showcased with stability and grace. The low-profile design minimizes snagging, making it an ideal choice for those seeking a ring that balances refined style with practical wearability.

Each piece reflects our commitment to ethical jewelry, featuring a lab-grown diamond option that reduces environmental impact while maintaining exceptional clarity and brilliance.

The gentle curve of the rose gold band complements a variety of hand shapes and sizes, and its streamlined form pairs effortlessly with stacking bands or wedding rings. This mounting is ready to accommodate your chosen marquise center, inviting a personalized touch to your engagement story.
