Not sure this is where to post this question or Pic's but figured I would start here. This showed up one day in my office. I keep a few pretty rocks on the conference table in my office. From time to time a new addition shows up. This is one almost to Cool to Cut up ..... but I haven't a clue what it is. I just call it the Opaque green Holy rock. Shot one Shot two Shot three Shot four Thanks for the feedback upfront! Dave

Looks shiny like glass or common opal. Somebody here will know.

Can you scratch it with a knife? It looks like the surface had been polished at one time and then struck numerous times with something sharp to cause the white pits. Bob

Yes - you can scratch it with a knife. Not easily, but it does scratch. The surface appears shiney in the photograph, that is for sure, but it really isn't. I just went and cleaned the surface with water. The surface with water on it feels ... Ummmm.... slick? Not sure that is the way to describe it. The matrix it is deposited on is soft too. The white pock marks come from being picked up and handled and put back in the pile on my conference table. On another note - has anyone seen this site with all the photographs? www.flickr.com/photos/97769244@N00/3899052569/in/set-72157610622211935/OMG. I just spent a half an hour wandering around Wonderland. There are two photographers and the photos are Beautiful and endless. Dave

Have you tried it under black light? My prehnite glows very well under black light, just the ordinary black light they used to sell in "head" shops. Here's one of mine, not too impressive except on the "black light" shelf where it loves to glow in the dark, alas I don't know how to photograph glowing objects. It does look like common opal but I sold this stuff back in the day and no one ever came back and said it was mis-identified. Supposedly Australian material, in my case.

I'd guess some kind of calcite or calcite onyx as acid rain often eats those holes in it over time.....Mel
