As I was carefully examining this specimen with the loupe, the seller - an obscure Catalan dealer - finally admitted, much to his embarrassment, that the fibrous material in the last image was the result of some poor repair work.

After a closer examination, he finally agreed to tell me the truth - these were just fibrous crystals of cummingtonite.

Thank you Jordi, honesty always pays off!


Hi Gérard. I am afraid you lost me . Did Jordi sell you a repaired specimen?????

As I was examining the specimen, I asked Jordi about the strange fibrous material that was covering the matrix, here and there.
He looked up to me and told me with a very straight face that he had to fix the specimen and was apologetic about the very poor repair work he had done.
We both had a good laugh and he finally conceded that the fibrous material was very likely cummingtonite.
Typical of Jordi's great sense of humor.

No repair, all natural.

the end the crystal is absolutely beautiful;
the base with pyrite and the elongated shape make a very special specimen.
On of your best I think.

Thank you for your comment Philippe.
It's a small but very well balanced specimen, quality wise, proportion wise, and composition wise.

Tobi, I wish I had a hundred of these to start ranking them :-)

Thanks Tobi.
It's one of the rare occasions where I spent more time checking the calcite than the emerald prior to making a decision. It's usually the opposite :-)
