Hydroxyapophyllite Agate I don't know how often

I don't know how often breaks occur due to rough techniques in mining or cracking the geodes open

introduced

365nm UV fluoresces a strong yellowish-green color

It's difficult to photograph to the back of the geode because it curves off into darkness

and a flat surface luster caused by etching

Hydroxyapophyllite Agate I don't know how oftenLocale: 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,
