Lab-Grown Diamond Engagement Ring

When sunlight catches the elongated facets of a marquise diamond, it casts a slender, shimmering silhouette that seems to dance with every movement. This semi-set solitaire ring invites you to choose a center stone that embodies that graceful, tapered drama—measuring approximately 6 by 3.5 millimeters—ready to become the heart of your story.

Crafted from warm 10K yellow gold, the band offers a gentle curve that balances the diamond’s pointed elegance with everyday comfort. The low-profile setting ensures the ring sits close to the finger, making it ideal for stacking or wearing alongside a wedding band without catching on gloves or sleeves. Each piece is meticulously finished in our Williamsburg studio, where hand inspection guarantees smooth edges and a refined polish.

Our diamonds are lab-grown, reflecting a commitment to ethical sourcing and environmental mindfulness without compromising brilliance or clarity.

This solitaire’s slender silhouette suits hands that appreciate subtle drama and refined geometry, especially those who favor a ring that feels as natural as it looks striking. The semi-set design allows you to select a marquise diamond that matches your vision, whether you prefer a delicate sparkle or a bold statement.
