编号 84442903
编号 84442903
Wonderful specimen of light blue aragonite on matrix.
It is possible to see clearly a first layer of aragonite (1.5 to 2.5 cm) surmounted by a stunning coralloid formation, particularly beautiful and aesthetic.
The underside aragonite has a more intense color compared to the coralloid one.
Beautiful specimen, very aesthetic and well crystallized.
