Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous shadow that seems to stretch across the hand. This semi-set engagement ring invites you to choose a 9 x 4.5 mm marquise stone, whose tapered points and graceful curves evoke a quiet drama and refined elegance.

Crafted from warm 10K yellow gold, the band is shaped for comfort and daily wear, its smooth finish balancing subtle presence with enduring strength. The solitaire setting is designed to cradle the stone securely while allowing light to flood every facet, enhancing the diamond’s signature brilliance without excess height.

Each lab-grown diamond reflects a commitment to ethical sourcing and environmental mindfulness, offering clarity and sparkle with a lighter footprint. The ring’s low-profile design suits those who favor understated sophistication, slipping easily beneath gloves or alongside stackable bands.

Should you need a custom fit, resizing is handled delicately in-studio to preserve the band’s integrity and finish. Lead times are transparent and tailored to your chosen stone and design preferences.
