Amethyst, citrine, rose, smoky and ten more: why quartz comes in so many colours.
This QuickStudy guide pictures 14 quartz varieties, from clear and rose to rutilated and super seven. It explains the trace elements or inclusions behind each colour, such as iron and titanium. You get one laminated card printed on both sides, sturdy enough for coffee rings.
It's a small revelation for new rock fans. It's honest too: the citrine entry notes it forms from natural heat in the earth or through artificial heating.
What's on it
- Side one: Quartz basics plus eight colour varieties, from clear quartz and amethyst to citrine and lemon quartz.
- Side two: How quartz forms, why colours vary, and six more types including phantom, rutilated and super seven.
How to use it
- Sort your quartz by variety
- Check what gives each colour its shade
- Keep it with your quartz points
Care: Store it flat or upright in a book, and wipe it down when it gets smudged.
The details
- Width: 160mm
