Looking for a bit of advice/help - found a stone on Embleton beach yesterday, and wondering what it might be. Walked past it at high tide, right at the edge of the tide with water lapping over it.
It's about 9cm, by 5cm by 1.25cm (at widest), looks like basalt, weighs 195gms.
Interesting bit is that it has a hole through it. Hole looks like it was worked in from both sides, but much more so from one side. On that side the hole tapers down from 2cm diameter to about 1cm, on the other side goes from about 1.3cm to 1 cm. In the center the narrowest part of the whole has been made slightly oval by what looks like wear (at about 11 o'clock in the 4th photo above).
This isn't at the point the hole would wear at if you put a rope through it now though.....
On one side the "walls" of the hole are lighter coloured due to what looks like some sort of "concretion"? Nothing similar on the other side. However on that side there is a second, partial tapered hole (0.7cm diameter at it's widest) that tapers out about 0.5cm into the rock.
So what does the panel think:
1) Man made or not - been caught out before and have posted on geology rocks forum to see if there are natural explanations.
2) If man made - what is it - loom weight? Fishing net weight?
