Lab-Grown Diamond Engagement Ring

Sunlight catches the elongated curve of an 8x6 mm oval diamond, its gentle fire unfolding like a quiet promise. This solitaire semi-set ring balances modern minimalism with architectural clarity, framed by a fixed two-tone band of warm 18k rose and 18k rose and platinum and cool 18k rose and platinum.

Crafted with precision in Williamsburg, Brooklyn, the slender 6-prong setting secures the stone while maintaining a lightweight feel that rests comfortably for daily wear. The low-profile mounting ensures the ring slips easily beneath gloves or alongside stackable bands, making it a versatile companion for a contemporary lifestyle.

Each piece is meticulously finished and inspected in-studio, highlighting the subtle contrast between the 18k rose and 18k rose and platinum shank and 18k rose and platinum prongs—a deliberate interplay of tone and texture that enhances the diamond’s glassy oval shape.

Ethically sourced, the lab-grown diamond offers clarity and brilliance without compromise, reflecting a commitment to sustainability embedded in every facet.

Designed for those who appreciate refined structure and confident understatement, this ring complements slender to medium finger sizes, its oval silhouette elongating the hand with quiet elegance.
