What is "brecciated"? Brecciated comes from "breccia"--a geology term used to identify rock composed of broken fragments naturally cemented together into a fine-grained matrix. This sedimentary matrix includes clear and smoky quartz, goethite, iron and blue chalcedony. Metaphysically it creates a great tool for grounding and centering. Adding this to your meditation tool kit is a must! And...they are beautiful too!
