3.1" Polished Agate Heart - Madagascar

Polished Agate Heart - Madagascar #210204

This is orca agate (a.k.a. “Orca Stone”) from Madagascar which has been hand-polished into a heart. This beautiful piece is 3.1" wide and has a mixture of blue, tan, and white agate in both mottled and banded formations.

Agate is a variety of microcrystalline quartz (chalcedony) that displays translucence and in some cases banding. Agate primarily forms when silica-rich fluids fill pockets within rock and/or fossils, resulting in deposition of the silica along the walls of the rock. This process can result in banding patterns as the composition and impurities of the fluids change over time. These banding patterns can either form as flat layers or rounded layers, depending on the surfaces available for deposition.
