Brown Crystals
Every brown stone in the database, with what it is made of and what it is traditionally used for.
Brown stones are the earth group, tied to endurance, patience and the long, unglamorous kind of persistence. They are what people reach for when the problem is not a lack of energy but a lack of ground under it. The colour is almost always iron staining, which is stable and hard-wearing, so brown stones tend to be the low-maintenance end of a collection.

Cacoxenite
Phosphate inclusion
Golden needles growing inside amethyst or quartz, sold as a stone of large-scale change.
Worth knowing: Cacoxenite is an inclusion rather than a standalone crystal. What is sold as cacoxenite is host quartz or amethyst with the mineral growing inside it.
Dalmatian Jasper
Feldspar rock
Cream with black spots, the stone people buy for children and for their own sense of humour.
Worth knowing: Dalmatian jasper is not a jasper. It is a feldspar-rich igneous rock, and the black spots are usually arfvedsonite rather than tourmaline.

Why the colour matters
Colour is the fastest way into the correspondence system, because the chakra scheme is itself colour-coded, and most traditional associations follow the colour rather than the mineralogy. It is also the least reliable guide to how a stone must be treated: two stones of the same colour can be a hard silicate and a soft copper carbonate, and only one of them survives a rinse. Each card above carries its own verdict, and the safety checker has the full reasoning.

Fact and tradition, kept apart
The mineral family, the Mohs hardness and the water verdict on each card are checkable physical fact, drawn from standard mineralogical and gemmological references. The chakra, element and purpose associations are tradition, published across the modern crystal-healing literature and offered here for reflection rather than as fact.
