Like agate, chalcedony is typically not considered a high-end collector mineral specimen. But sometimes, chalcedony as well as agate qualifies nobly; as with this large, striking specimen! This botryoidal, taupe-colored chalcedony is lustrous and translucent, so that you can see a generation of whiter chalcedony as internal phantoms within the finger-like forms. Really dramatic! 23 x 12 x 3.5 cm
