The human story, examined
Documented history, historical belief and contemporary crystal practice are different parts of the story. Each is identified here on its own terms.
The human story
In the gem trade, “chalcedony” often means relatively uniform material, even though the wider family includes many named patterns.
Reading a name carefully
Is the name describing the actual material, a pattern, or a claimed locality? Keep those three parts of the label separate.
Sources & further reading
References are labeled by role. A source documenting a belief is not evidence of a medical or mineralogical effect. Reflection prompts are C&C editorial suggestions.
