I found this mystical object in a river nearby where I live in Norway.

It was lying unscathed and in perfect condition without a scratch amongst stones and sands in the middle of a river.


No one has been able to tell me what it is. I found it two years ago, and am now trying to find someone that can identify it, because it's characteristics does not make any sense to me.

I have now contacted and been replied by National Geographic (did not have any staff that could identify the object) from them I was referred to NGI, Norwegian Geological Institute who neither had any expertise in identifying objects found in the ground. I am also waiting for a couple of more instances to reply to my inquiries, a.m.o some archeological ones, however, I doubt I will get any answers.

It weighs 15,3 grams, measure 2,6 cm diagonally, 1,4 cm vertically and is 0,6mm thick. The four sides measures about 2,5cm. The metal looks grey but has a rainbow coloured hew over it as one can see from the directly frontal shot. It doesn't look like anything that I know. It feels very heavy to hold for it's small size, too heavy for jewelry, too perfectly cut/designed to be a common part of an engine or any machine, at least of what little I know; not that I am anything of an engineer. It looks like both a decorative artifact as well as one of practical use. I can't help being curious.

Anyone?

wtf

WOW...How did you find something that small in the middle of a river? :o

It looks to be painted or coated preventing corrosion. The round center looks to be a different piece. Is it assembled from two pieces? Can you see any rust or corrosion inside? Can you scrape away the surface in an inconspicuous place to see the base metal?

Can you tell us the inside diameter?

There is no- one fishing this far down the river, but a few miles up the stream there would definitely be some fish of small size, most people who would fish in the lake itself. However, I haven't seen fishing equipment that look like this though;)

Pendant? Could possibly be... Can't say it aint.

The river runs out from a bigger natural lake from the higher up in the woods through our small village into the sea.

I found the object as I was picking some broken glass away from it as my kids were standing in the river playing. Picking glass, there is was.

The diameter of the hole is a tiny bit more that 5mm (ca 0,55 cm) I'm afraid I have no idea what that would be in your measures.

bigcyprusshunter - at first I thought you were right, it looks like the ring inside is put there... then I cleaned it thoroughly , and I must say I it really looks like one piece. Scraping the inside doesn't do any good, no change in colour only slightly darker that's all.

well, it's night time overe here, I'll be back tomorrow to look for any new posts - so later guys, and thanks for the input so far.

Wtf

I think what you have found there is a carbide or ceramic metal cutting tool insert...

The shape is right for a cutting tool, but the coating and pattern on it could be anything or smooth, depends on what was being machined and if they have chip breakers on it, type of coolant, metal thickness, etc...

Cool item, question is how did it end up in a river? ...lol...

A whole lot of "Iff's) here but I'd like to suggest a fishing leader spool,dispenser & cutter. It's kinda like a dental floss dispenser. If the tabs at each point would cut line and If the hole would hold- say 50 feet of light leader material and If I'm not too delusional today. A picture just to see the theory.

Oh well. I thought this one would last longer. Turns out there is nothing mysterious about it. Its a tungsten carbide cutting tool insert. Good ID steif. :thumbsup: http://dywyhj.en.alibaba.com/product/212604923-200274333/carbide_indexable_inserts.html inserts_tungsten_carbide_.webp

Good ID Stief! :thumbsup:
I just wished that I'd got into this thread earlier because I can second the ID!
The wavy pattern atop the insert helps to form the chips so that they come away from the area being cut. It used to be that chips would wrap around or build up then slip into the path of the cut causing a flaw in the surface finish. These inserts are mostly used on turning lathes but have also come into use by milling machine cutters too. The rainbow finish might be from getting hot during machining. They are usually made from carbide, a sintered metal, which is very dense and seems heavy like lead.
