Also called rock crystal, crystallus, krystallos, master healer (modern crystal lore)
Clear quartz, or rock crystal, is the stone that gave us the word crystal: Pliny believed it was ice frozen so hard it could never melt. It is the stone of crystal balls and seeing stones, and modern practitioners treat it as an all-purpose amplifier for intention.

The working
Set the glass of cold water beside the quartz to recall Pliny's belief that rock crystal was ice frozen forever.
Write your intention as one clear sentence, such as finishing a course or keeping a promise to yourself.
Light the candle and hold the quartz between your eyes and the flame. Watch the light bend inside it for a minute or two without trying to see anything in particular.
Read the sentence aloud, then lay the paper flat and set the quartz on top of it.
Leave the stone on the paper on a windowsill for a night under the moon, and away from direct sun, which a sphere can focus into a burn.
In the morning, keep the stone on your desk or altar as a daily reminder of the sentence.
Take care: A clear sphere can focus sunlight and has started real fires, so never leave one in a sunny window. Points have sharp tips; keep them away from small children.
Versions across time and place
i
Frozen ice of the Alps
Roman natural history · 1st century CE
Pliny writes that crystal forms where winter snow freezes hardest, that its Greek name comes from ice, and that the best came from India and the Alpine heights, where men hung from ropes to reach it. Empress Livia dedicated a block of about 150 pounds in the Capitol.
Recorded in: Pliny the Elder, Natural History 37.9-10
ii
The physician's burning ball
Roman medicine · 1st century CE
Pliny reports that doctors considered a ball of crystal held in the sun the best cautery for the human body. It is one of the earliest written mentions of crystal spheres and a reminder that a clear sphere really can start fires.
Uses: crystal ball, sunlight
Recorded in: Pliny the Elder, Natural History 37.10
iii
Grave globes and seeing stones
Merovingian, Anglo-Saxon and Elizabethan practice · 5th to 16th century
The Frankish king Childeric I (died 481) was buried with a small crystal globe, and similar balls appear in later Merovingian and Anglo-Saxon graves. By the 16th century John Dee and his scryer Edward Kelley were using a crystal shew stone to seek visions of angels.
Uses: crystal sphere

History
Clear quartz is silicon dioxide in its purest crystal form. The Greek krystallos meant ice, and Theophrastus in the 4th century BCE already listed crystal among stones used for engraved seals. Pliny the Elder, writing in the 70s CE, stated in Book 37 of his Natural History that crystal forms from extreme freezing and is a kind of ice. He described miners on ropes in the Alps and a 150-pound block dedicated by Livia in the Capitol, and he noted that doctors used a crystal ball in the sun to cauterise.
Crystal spheres were buried with Merovingian royalty, and crystal gazing for visions spread through medieval and Renaissance Europe, most famously with John Dee's shew stone. The Victorians revived crystal balls in parlours. Modern crystal practice calls clear quartz the master healer and uses it to amplify intentions; that is belief. Crystal healing has no scientific support: in a 1999 Goldsmiths experiment by Christopher French and colleagues, volunteers holding fake crystals reported the same sensations as those holding real quartz. Glass and lab-grown quartz spheres are sold widely, and many cheap clear points are glass.
