Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated silhouette of a marquise diamond, casting a slender, luminous shadow across the hand. This semi-set solitaire invites you to select a center stone that balances bold geometry with delicate refinement.

Crafted from warm 18K yellow gold, the mounting features a slender band that tapers gently toward the pointed ends of the marquise shape, enhancing its architectural drama. The setting is designed with a low profile to sit comfortably beneath gloves or daily wear, while the artisan finish reveals subtle hand-polished facets that catch light from every angle.

Each ring is made in our Williamsburg studio with lab-grown diamonds, reflecting a commitment to clarity and sustainability without compromise. The ethical origin of the stone aligns with a modern approach to fine jewelry, marrying beauty with conscience.

This solitaire suits those who appreciate a statement piece that remains wearable—its slender band and secure prongs offer a confident fit for slender or average finger sizes, and its elongated shape visually lengthens the hand. Ideal for stacking or wearing solo, it adapts seamlessly to evolving personal styles.

Should you need resizing or prefer a custom stone, our Brooklyn studio offers expert adjustments and guidance, ensuring your ring fits perfectly and shines for years to come.
