Hedenbergite quartz point with sprouting growth Chalcopyrite UV reactivity The white calcite

UV reactivity The white calcite fluoresces moderately well under 365 nm UV light

a close relative of chalcedony and quartz

They have a tendency to "greet light" and stand up in curiosity when you shine light on them (I mean

Some types of purple fluorite phosphoresce

This specimen has good reaction

Hedenbergite quartz point with sprouting growth Chalcopyrite UV reactivity The white calciteLocale: HuangGangLiang mining district, Inner Mongolia, China Approx point length: 2. 25" Approx weight: 55g These quartz points are from HuangGangLiang, and commonly called Mongolian or Inner Mongolian quartz. When the primary inclusion is hedenbergite, enough to give the quartz a greenish tint, it is more appropriately called hedenbergite quartz. This isnt your typically shiny quartz crystal; the points have a matte luster with a sheen effect,
