Agatized Fossil Coral Specimen order

Product Name: Agatized Fossil Coral Specimen order
Agatized corals are fossils formed when silica from groundwater replaces ancient buried corals (as opposed to typical calcite-replaced fossil corals). They consist of void fossils that have been filled with various forms of quartz (another name for silica), primarily one called chalcedony, and, in some cases, both chalcedony and rock crystal quartz (quartz that is clear with large visible crystals terminated by crystal faces). The term “agatized” refers to the variety of translucent chalcedony called “agate,” which has very small crystals (micro- or cryptocrystalline), and is characterized by banding and rich coloration, properties that are common to agates worldwide. UV reactive stunning black color with order druzy.
