T here are blue diamonds… and then there’s The Mediterranean Blue.
In this episode of Frank’s Files, Frank Everett is joined by Lauren Harwell Godfrey, founder and designer of Harwell Godfrey fine jewelry, for an up-close look at a 10.03 carat Fancy Vivid Blue diamond that has captivated gemologists, collectors, and scientists alike. From its formation over 3 billion years ago to its half-year-long cutting process, this masterpiece is more than a jewel—it’s a window into Earth’s deepest, most oceanic secrets.
Only 1% of blue diamonds ever reach the Fancy Vivid grade, and fewer still carry the visual poetry and scientific marvel found in this stone. As Frank and Lauren explore its electric color, elegant cushion cut, and connection to ancient oceans, get a rare glimpse into how nature, science, and craftsmanship collide. The Mediterranean Blue isn’t just rare—it’s revelatory.
The Mediterranean Blue is the star lot of Sotheby’s High Jewelry featuring The Mediterranean Blue, taking place live in Geneva on 13 May at 4:00 PM CEST.
