Featured Modern Bjorg Norwegian Designer Herkimer Diamond Quartz & Nail Necklaces

Yes, you did read that right, a stonking great 4” nail!
Just wondering if anyone was aware of this brand as I’d not heard of it before.
Two necklaces I picked up today because they looked interesting. Turns out they were a good pick at £1.75 each as they are quite expensive.
The nail one has ‘I can do anything’ on it. No idea the significance of the nail, it has a slightly uncomfortable crucifixion feel about it
The other one I haven’t pinned down on line yet, just a similar Sterling one in a cube cage.
Not sure what the metal is, the one I found on the internet says the nail is 18k plating over bronze and the other one I have no idea.
Looking on their website they have similar stones in rings in their Herkimer Diamond Collection so I presume this is the same gemstone, but what is the black inclusion? Is there such a thing as black quartz?
Thanks for looking

 

Yep, that is (black) onyx. Black inclusions in quartz are commonly tourmaline.

 

If it is an actual Herkimer crystal, the black is likely limestone matrix.

I have a Herkimer diamond with similar black:

 

I don’t think I’ll ever get my head around all the types of stones!

Beautiful! I’ve not come across them before.
I think it is HD as the website has a ‘Collection’ of pieces.

 

Maybe it's Pakimer crystal,sold by the kilo from Pakistan.

 

Maybe. Wouldn’t be the first time a manufacturer has used a cheaper substitute to cut costs. Unless there is a way of testing I’ll probably never know!
This is quite interesting lower down where they explain the difference.

Yep the naming system is a complete mess due to people not realising many crystals were the same thing back in the day as they were unable to test effectively. I think there are about 30 names for chalcedony now, and calcedony itself is a form of quartz. Then there all the modern egregious names which are pure marketing crap.

My references suggest black inclusions in these are usually hydrocarbon which is interesting - so coal or even some oil in liquid phase inclusions.

 

How cool would that be!

 

I know that there are Herkimers that are crystal clear - no inclusions. Beautiful things.

Back in the '60s, my father and I belonged to a local rock club (Geological Society) that made an annual trip to Herkimer. We never went. That stopped when an interstate went through that paved over the prime collecting ground.

 

Isn't that always the way.
