Communication, listening and understanding are the topics for which blue chalcedony is used in modern gemstone healing. Blue Lace Agate is therefore also known as the "speaker's stone".
The terms "chalcedony" and "carchedony" were first used by Pliny the Elder in his Latin Naturalis Historia in the 1st century AD. However, it is not possible to clearly identify which stones were described here on the basis of the descriptions. Via "intermediate stages" such as calcedony, calcedony, chalcedony or kalcedony, the name changed to the chalcedony commonly used today.
