Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of the marquise diamond, casting a slender, confident shadow across the hand. This semi-set engagement ring invites you to choose a center stone that balances architectural grace with modern minimalism.

Crafted from warm 14K yellow gold, the band is polished to a soft sheen that complements the marquise’s sharp elegance. Accents frame the setting with subtle precision, enhancing the diamond’s clarity and structure without overwhelming its form. The low-profile mounting ensures everyday comfort, while the smooth band feels natural against the skin.

Each lab-grown diamond is selected for its ethical origin and sustainable footprint, reflecting a commitment to responsible luxury. The semi-set design allows for a personalized center stone, tailored to your vision and lifestyle.

Ideal for those who appreciate clean lines and a refined silhouette, this ring suits slender fingers and pairs effortlessly with stackable bands or a wedding band. Its streamlined shape slips easily under gloves or sleeves, making it a practical choice for daily wear.
