Agatized Fossil Coral Rock Slab 20
This amazing lapidary material is the agatized remains of fossil coral from Indonesia. The intricate calcium carbonate skeletal structure of ancient coral has been replaced with silica, preserving the amazing detail of the internal structure of the organism. Beautiful “eyes” are revealed when the rock is cut at right angles to the coral columns. Mostly browns and greys, but occasionally red, pink and purple, the colors and patterns make spectacular cabbing material.
Dimensions: 2.75" x 3.25" and approximately 6.1 mm thick. Weight = 83 grams.
Shown wet. Not polished. Flaws are shown as white lines in the last picture frame.
