Grand nodule de septaria scindé en deux parties

Large Septarian Nodule 'Split'
Belgium
This uncommonly large Septarian nodule split displays multiple aesthetic contraction grooves. Each half has been finely polished to show an inner beauty as gray Limestone, yellow Calcite, and brown Aragonite interplay forming an orchestrated combination of complementary hues. Septarian nodules are basically a clay concretion that has had its hollow cavities filled with mineral rich fluids over thousands of years which crystalized over time and preserved the cracked patterns seen here. Each half measures approximately 40 cm (4)
