Botryoidal Chalcedony – Large Dome Formation – Maharashtra, India Pyramid It was developed by PeterA classic specimen of botryoidal chalcedony featuring a well formed larger dome and smaller chalcedony growths. The surface exhibits a smooth, natural luster with a soft reflective quality and subtle translucence. Formed within a volcanic cavity in the Deccan Traps, this piece represents stable silica deposition that allowed for the development of thick, rounded botryoidal forms.
