This piece of agatized coral is from the West coast of Florida around the Tampa Bay area. It is a remarkable specimen of agatized coral containing boytrodials, stems and druzy with colors ranging from dark grey to almost white. I have shown it one way, then upside down. It is one of those pieces you have to hold to see all its beauty.
It is 4" x 3.75" x 2.25". A nice piece for your collection.
