Chalcedony
Chalcedony
Chalcedony is known as cryptocrystalline quartz, from Greek word for “hidden”, because it is made up of tiny quartz crystals that are invisible to the unaided eye.
Chalcedony quartzes are abundant, semitransparent to opaque gems that include patterned and banded agates, intense blue-green chrysocolla – in – chalcedony, and yellowish green, jade-like chrysoprase.
Crysocolla – in – chalcedony is one of the most valuable chalcedony varieties. The sources include the US, Mexico and Israel.
Carnelian and Sard are warm-hued chalcedonies. Carnelian’s current sources are Brazil, India and Uruguay.
Iris agate shows iridescent colours phenomenon when light is transmitted through thin slices.
