The Crystal Reference — 38 Stones, What They Are and How to Keep Them

Thirty-eight stones, one card each. What the stone actually is as a mineral, how hard it is, what gives it its colour, whether it can go in water, and what people have traditionally used it for. Photographed from real stones, not illustrations.

It exists because most crystal guides are vague where it matters and confident where it shouldn't be. This one tells you that selenite dissolves, that malachite is a copper carbonate that should never be soaked, and that most citrine on the market is heat-treated amethyst.
