Scepter Quartz is a distinct quartz habit where a larger, younger crystal forms at the termination of an older, thinner stalk, creating a mushroom-like or scepter appearance. It forms in hydrothermal environments where a sudden change in conditions triggers rapid secondary growth on an existing crystal tip.

Is this scepter quartz?

5-step field check

Run through these checks against the specimen in your hand. The more boxes tick, the more confident the ID.

1
Test the hardness
Try to scratch scepter quartz with a known reference. Scepter Quartz sits at Mohs 7, softer than the next harder reference, harder than the previous one.
2
Check the streak
Drag the specimen across an unglazed porcelain plate. Streak: white.
3
Read the luster
Hold the specimen under a strong light. Luster: vitreous.
4
Match the color range
Compare against the expected color range: colorless, white, smoky, amethyst, citrine.
5
Look at form & habit
Crystal system: trigonal. Typical habit: scepter-shaped; a thicker head of crystal perched atop a thinner stalk.
