Prehnite finger cast after Anhydrite

Prehnite finger cast after AnhydriteA representative specimen of Prehnite fingers after Anhydrite with a darker green color, and a coating of a secondary clay mineral. Overall, the piece is actually in good condition, with a predominant finger flaring out of the center of the piece. The color in the photos is accentuated by the lighting we used to photograph the piece, but it is a bit more muted in person. The Prospect Park Quarry is arguably the most famous mineral producing basalt

and if you collect this material

1 cm across sitting beautifully on the underlying Quartz matrix

I’ve seen twinned Sapphires with blue and yellow hues in the same crystal

layered groups of Bertrandite measuring up to 2

The piece has a light coating of a secondary clay mineral but does display well from several angles

A fantastic and very rarely seen MATRIX specimen of the "champagne" color Petalite from a recent find in Myanmar (Burma)

but what really sets it apart is that it contains several wispy inclusions with varying orange to pink hues that create eye-catching color combinations when the piece is backlit

showing crystallization on all sides with some minor attached white Microcline
