Agatized Fossil Coral Rock slab 77
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 grays, but occasionally red, pink and purple, the colors and patterns make spectacular cabbing material.
Dimensions: 6.5" x 3" and approximately 11.4 mm thick . Weight = 223 grams.
Shown wet. Not polished. No significant flaws.
