Hi KDF,
I believe your specimen is more likely to be rosasite with calcite instead of hemimorphite

Hi Jean, I did question that too when I pulled up the pictures yesterday. The label says "Rosasit, Hemimorphit". Anybody else?
Here's one of my favorites.

That adamite is incredible...I WANT IT (see what I mean about focused covetessness!).
Here's a bunch more on Ojuela...minerals, sections, old pictures and articles.

Carles,
thanks! I like your database of course and i am busy to move the old records to the new and add some 200 specs continuously ;-). Last Ojuela for this year:
Width of picture approx 3 cm. Another one of the recent Wulfenite/Mimetite combos.
cheers
Roger
