Please help identify old hexagon shaped rock
« on: 26/11/2014 06:29:28 »
Ν

I received this rock over 30 years ago from an avid arrowhead collectors collection.  I would love to find out what type of rock it is and if it was naturally formed or cut/carved.  It fits perfectly in the palm of my hand and is very heavy.  As far as I know, it was found in Kentucky.  Each side appears to be a hexagon shape.

Hmmmm
Is it at all translucent if you shine a bright light either behind the rock, or directly into it?

the color, density and dodecahedral shape all suggest garnet.

If I found that in Cornwall, which is where I did most of my mineral/rock hunting, I would first try to scratch it with my "trusty blade", and if that made no impression on it I would think in terms of almandine garnet.   

If that's what it is, it's quite a find.

The OP has replied to this question via PM.
No, it is not translucent at all with a light shining on it.  It is very solid and heavy.  Feels like iron or something.  To me, it appears to have been man-made or carved somehow.  I have tried and tried to find something like it online but cannot.  I tend to believe it was a tool, like a hammer or something attached to a handle.  There is a deep gash on the one side of it.  But all sides look like a hexagon.  I am a novice so I'm simply guessing.  I feel an energy or attachment to this rock, it's very interesting.  Though it looks rough, it is actually very smooth on the sides and soothing to hold in your hand.  A couple of the sides have pyramid like shapes in the middle of the hexagon shape. 
[...]
Even though it looks rough, it it smooth to the touch. 

I have very little experience with raw uncut gemstones, but it would seem to me that a garnet would be translucent at least to some extent.  Are there different types?

Have you tried scratching it?

Knowing its hardness would be useful.


You could measure the density (drop it into a measuring beaker of water and check how much it increases, then divide its mass by the volume).
