The Story
These stones were Sally’s for forty years. She chased the extraordinary — alexandrite that shifts from forest green to raspberry red, black opal holding an entire spectrum in one stone. When she left them to us, we decided they should keep travelling.
We hope it’s as meaningful in your collection as it was in ours.
