Teal blue-green Prehnite from basalts in the Goboboseb area are not at all common and this is a very good small cabinet piece from a limited find out of Charlie Key's personal collection. For that matter, sparkling blue prehnite is almost unheard of, from anywhere! This is a large and lustrous radial fanned aggregate of translucent to nearly transparent, medium teal-green Prehnite that you can see part way into! It is composed of relatively large and fairly distinct, tightly grouped, bladed crystals that arc around the entire Prehnite aggregate with the scintillating terminations reflecting any incident light as you rotate the piece! A lovely small cabinet piece, of unique appearance, from the significant Namibian collection of Charlie Key.
