Heat Treated Florida Agatized Coral Cut Slab

A striking heat-treated agatized coral slab pair, showcasing rich golden amber tones framed by natural blue-gray and cream banding. Formed over millions of years beneath Florida’s ancient seas, this fossil coral has been carefully cut and preserved to reveal its dramatic internal structure and layered mineral transformation.

These slabs offer exceptional contrast and depth — ideal for lapidary artists, collectors, or anyone seeking a rare natural specimen with museum-grade presence. The organic edges remain untouched, highlighting the raw authenticity of the material while the polished face displays the coral’s agatized heart in full detail.

Perfect for knapping, future cabochon work, or as a centerpiece in a collection.
