Michael, the celestine from Poland (Celestine, Machów Mine, Tarnobrzeg, Podkarpackie, Poland) is very interesting.

| I like the reddish blue-cap elbaite from California! It's a small relative of a lot of famous tourmalines that came from that area ...

Thanks Don,
This was one of two minerals that were on my wish list for Denver. I was very happy to see Valere Berlage set up at the Marriott Show and he had several very nice pieces to choose from. By the way, the other piece on my list was the ram's horn gypsum from Morocco that I posted a few days ago. So, I consider myself fortunate to have found both pieces.
Say hello to Gwen.
