I am interested in examples of cleavage in azurite crystals.

Does anyone have any pictures of these?

[James Catmur]

I used to have some cleaved azurite specimens, but they have left the collection and I have no images of them

Aniol

I think he means broken crystals (cristales rotos) so that he can see both the good and poor cleavage in azurite

Thank you both for clarifying it.

They pretty much broken. I was curious cause traductor issue I guess.

The person who sold it to me is from Midelt so I didn't ask too much the location, but theoretically not far from there.

Please use a spell check before posting

Hello,
I don't think I've ever seen an azurite cleavage.
Here is an old specimen of Tsumeb (Willy Israel) without any breakage but whose termination of a crystal is not harmonious.
Blemishes are growth defects, however with a small conchoidal fracture that looks natural.

Hi, All

I also have never seen a cleavage in azurite.
But, despite this, in Klockman 14th edition in German (mine is in Spanish...) there is a quite perfect cleavage in (100).
Mindat says
Perfect on {011}; on {100} fair; on {110} in traces.
Agreed that Mindat is more modern, but I fail to see why in Klockman there is not even a mention on the cleavage on (011).
But I should say also that I am sloppy in Miller indexes.,.... :-(

With best wishes
