2.45" Polished Green Opal Sphere - Madagascar
This is a 2.45" wide, polished green opal sphere. This unique stone has a rich, pistachio-green color and interesting patterning. It comes with an acrylic ring display stand.
Green opal is an amorphous variety of quartz, with the chemical composition of SiO2 · nH2O. This hydrated silicate mineraloid has the associated chemical composition and lack of crystal structure that terms this mineral conglomerate as an opal.
During formation, microscopic holes form within the silica, forming secondary silica lamellae-like strings throughout, giving the rock its inner web-like appearance.
