exceptional heart made of green agate and rock crystal with great crystal opening

A heart of green agate with a rock crystal druse from Brazil. The front shows a crystal opening studded with clear rock crystals. The back has been additionally ground and polished.

The material is natural. Only the heart shape was ground; nothing was dyed. The crystals inside remained untreated and naturally grown.

The piece comes from a roughly 100-million-year-old gas bubble from a volcano. Chalcedony and agate formed inside from silica-rich fluids, followed later by rock crystals as the youngest generation.

A double-sided object with green-blue marbling, a clear crystal opening, and a volcanic origin context.
