PostPosted: Dec 21, 2017 17:23    Post subject: Collection of Bergur E. Sigurdarson  

No images in my first post. Just an announcement of what is obviously to follow :-)

I started collecting rocks as a kid, always loved finding crystals as they are not that common in my home country of Iceland.
Even though a name-locality for Iceland spar, most of the country is so young that we don't have much to find in most areas. The most common being calcite, quartz and about 30 different zeolites.
I didn't have a good collection, mostly stuff I'd found at the beaches, which had lost most of it's proper crystal faces after being rolled around in the surf. My aunt gave me a few she bought in Denmark, and although they did originally have their info with them, I didn't think that was of any importance, being just 10.
As a teenager I lost interest and also lost most of the rocks I had collected as my parents moved after I had left home. It wasn't until about two decades later that my interests got reignited.
A trip to the east of Iceland, where the rocks are older than around the capital and thus much more crystals to be found, as well as other factors were a big part of this.

I now have a growing collection from Iceland (though I'm not aware of many others collecting here and not aware of a club at all). I have a connection to Colombia which means regular trips there and that helps in getting my collection growing from there. And finally roadtrips in the U.S. mean a growing collection from there too.
I prefer to have a personal connection to my rocks, rather than just buying from random places I've never been to... so ... although a few may get in from places unknown to me, most are my finds or acquired by me in my travels to the places of origin.

And with that I can start postings of my collection :-)

This is probably my favourite emerald specimen.
I already posted it elsewhere on the forum (different picture) and hope this image is better.

Each emerald is around 2mm on the top, and they grow 2-4mm out of the rock...
and nearly all are perfectly terminated and after a rough count, there are around 150 !!!

Can't blame you for this start.
I would say Chivor but it could well be Muzo - all Colombian emeralds are from Muzo right?
In Bogota, always challenge the ones who know and trust the ones who don't.

Also love this large emerald crystal.
With a smaller second to the side, which has broken and mended (has a kink in it).

Main Emerald dimensions : W 10mm x D 9mm x H 21mm
Secondary dimensions : W 5mm x D 5mm x H 8mm (which may extend a bit further inside specimen)

Bought right from the miner himself in Muzo (out by the mines).

I've been travelling lately and thus not many posts of either what I had in my collection or what has been aquired this year.
While I'm still on the road, I just had to add this awesome parisite specimen I just got a few days ago. Could do with some cleaning to really make it shine, but still very presentable.

Hi Bergur,
Congratulations, that's a fairly large crystal for Muzo!

Some of these geometrical patterns look rather like contact areas to me!

Hey :-)

I'm quite certain those aren't contact points, as that is the end of the crystal that is on the inside of the vug of the specimen (towards the dolomites and quartzes ...left in first photo)

regards,
Bergur
