Description

HydroxyapophylliteLocale: N'Chwaning II Mine, South Africa Approx dimensions: 3 x 1. 25 x 1" Approx weight: 85g This specimen features hydroxyapophyllite crystals with lizardite and calcite on matrix. Properly called "hydroxyapophyllite (K)," hydroxyapophyllite is a variety of apophyllite that is typically colorless. It more frequently grows cubic crystals, but these specimens from the renowned N'Chwaning Mines region form tabular square crystals similar to wulfenite,

but this creates an interesting effect

The small dark spheres included inside the crystal and dotting the surface may be goethite or hedenbergite

I soaked it and picked away at the dirt with a toothpick

UV reactivity Under 365 nm UV light

The peridotite would have formed in the upper mantle but pieces of it became entrapped in magma during the eruption that transported it to the earth’s surface

Limit handling and do not place stress on repair joints

The surface texture on the main point is an intriguing patchwork of red druzy on and intergrowing with a translucent surface layer

but it's still one of my favorites due to the exquisite details

These minerals have only been found in Western Sahara

so it can be especially captivating in bright light or when lit from beneath

the hole in the front was packed with dirt

roughly resembling blood on dragon scales
