Hi John!

You get up really early every day! I hope you don't suffer of insomnia. I do it much later...

Now about the schorl: I'm sure any person wiser than me, probably yourself, just by observing the upper termination with a loupe, would easily be able to find out why the faces are so rough in contrast with the ones forming the prism walls.

Pyrite

Group of octahedral {111} crystals. Overall size: 64 mm x 56 mm. Main crystal: 52 mm tall, 42 mm on edge. Weight: 242 g. Complete all around. Note that each vertex shows what seems to be two small pyritohedral {210} faces (or perhaps rhombododecahedral {110}, very uncommon in pyrite).

If you love the octahedral pyrites as I do please see a similar specimen at https://www.mineral-forum.com/message-board/viewtopic.php?p=2663#2663

Carles,

That Babingtonite is simply stunning and great contrasting matrix of Prehnite and Quartz.
Congratulations
John

To Jon Mommers:

I'm very glad you like it.

Thank you for your comment.

The photos are just fine, Carles, and the piece is exquisite. Thanks for sharing your beautiful specimens.

Hi Tracy!

I meant I would like to be able to get better photos from my specimens. But as you already know it's not an easy task. Some of them are especially hard to be shot and it's very frustrating when you're unsuccessful after many tries.

You have a lot of good photos at your section. I especially like this hematite: https://www.mineral-forum.com/message-board/viewtopic.php?p=1092#1092 Please, keep posting.

Hi Carles,Seems there is a mistake about the dolomite from Peru,seems the sample on the pics is a Baryte.

[John S. White]

Carles you are too modest, your pictures are outstanding and I am enjoying all of them.

Hi!

I guess you are talking about this Baryte https://www.mineral-forum.com/message-board/viewtopic.php?p=5707#5707

First of all, I must state that the matrix of my specimen has not been chemically analyzed. But its apparent density, when held in my hand, does not seem to be the typical density of the Baryte. What's more, Jordi Fabre told me one week ago it was dolomite, and some other similar pieces at Mindat, coming from the same locality, are described as having a matrix of dolomite/dolostone. I believe dolostone is like limestone but made of dolomite instead of calcite.

Anyway, I thank you for your interest.

Hi John!

I've never been modest. Just realistic. My reference is Jeff Scovil, so in no way can I acknowledge my photos are 'outstanding' as you so kindly say. I'm learning and making some progress. However, I'm very glad you enjoy them.

Many thanks once again for your comments that I much appreciate,

Hi Carles, Really sorry, I did'nt see the title of the photo....that is Baryte...Dolomite was, like you said, the matrix....
really sorry not to have seen the evident title...

Don't worry. No problem. I also make that kind of mistakes from time to time!
