Design Intent
This design was created to bring together vintage character and modern precision.
At the center sits an elongated old mine cut — a stone known for its depth, movement, and unique facet pattern. Surrounding it, four marquise diamonds are set in a custom illusion layout, creating a wider visual spread while maintaining a clean, balanced silhouette.
Finished with diamond-encrusted prongs, every angle of this ring was designed to catch light — not just from the top, but from every direction.
