Description
Type Of Onyx: Blue Onyx. Blue onyx is a variety of onyx, which itself is a type of chalcedony (a cryptocrystalline form of quartz). Its blue color is caused by the Tyndall Effect, where light scatters due to the presence of tiny colloid-sized particles, similar to how the sky appears blue.
