Hi dear boss Jordi.

Thank you very much for your message.

I am posting two new photographs of this fluorite in order to help identify the locality. Both shots are with LED lights, not natural light.

Certainly was lacking a natural photograph as you ask, but they were turning out more tasteless for me.

I add the purchase was at Expominerales Madrid (Spain) in March 2013, in the stand of Félix Gómez called Krystalia. I also bought from him two fluorites from the Moscona Mine (Asturias).

Really, thank you for changing the orthoclase example from Gualba, very near to your city. Nobody better than you to know this specimen.

Sorry for the job I brought up, but I had this piece labeled as orthoclase.

Best regards.

Hi Jordi.

I thought so, from La Viesca.
I had seen some finer and more transparent but with the same growths and morphology than this one. And with very seemed ghosts from the Geoda del Tiro in La Viesca Mine.

Thank you for your valued opinion.

If you want to add “La Viesca Mine, Zona minera de La Collada, Oviedo, Asturias” will be perfect.
Thank you.

Calcite from Tunisia.
Both halves of this geode have dog-tooth calcite crystals, and specially in the left the growing is like a cactus. The two halves fit perfectly together, and there is no damage outside.
Was purchased in 1998 in the Chebika´s oasis, near the Algeria border. One of the first pieces in the collection.

Bariopharmacosiderite from María Josefa Mine, Almería, Spain.

Quartz from San Cristobal, Santander, Colombia.

Fragile spiny clear quartz with long skinny needle crystals forming 3D sculptures. This spiky piece presents colorless crystals to over 5 cm some of them totally lying and doubly terminated.

It is nice to see the birth of some crystals from the matrix.

I truly love the delicacy of the thin pointy crystals of this specimen.

Gérard thank you for your words.

Very interesting for me to know quartzs of San Cristobal have been seen in Munich this year.

I think that in the collectioin there are three clusters, more or less large, from this locality. The remaining ones are smaller or single crystals.

Now in 2017 I usually find in Medellín more specimens from Peña Blanca Mine, Boyacá Department. I´ll share all these new acquisitions that I have rescued in this city. And I´m very glad this new seller is more precise than others.
