Point length: 4"

UV reactivity Moderate white fluorescence when exposed to 365nm UV light

Ferruginous quartz is typically fairly opaque due to the density of iron oxide inclusions

so you may not see much surface-roaming until they are fairly established

which will fluoresce under 365nm UV light
