Spearhead (red Sandstone) With Gold Inside?

There was a thread here the last couple weeks about choice of scales.  My approach is to get an affordable set of scales and an affordable set of calibration weights.  The latter don't lie and will tell you when your scale is doing so.  ?  But if that's the case, I can make a calibration curve in the worst case that translates a reading to an actuaI reliable value.

I have four scales -- one a hanging scale (for multi-kilogram range) and three smaller, each one covering a least significant digit range (one, two, and three decimal place) for the gram scale.  As far as top end (max weight before overflow), I try to find one with the largest capacity which still fits my number of gram decimal place requirement.  My total investment for four scales and calibration weights is under $100.  I bought them over 5 years ago and all still work and are accurate.

Gotta figure out what this is in this thumb scraper now. See attached.

That is a little cavity lined with quartz crystals. That can happen quite often in flint, chert, chalcedony and agate since they are cryptocrystalline forms of quartz. Any crack, crevice or cavity within those varieties of quartz can make enough room for secondary deposits of quartz along with other minerals including gold to form crystals.

Nice. All kinds of nice surprises. Multi-layered entertainment.

Even if your spear point is modern it could still be gold in it, have it tested with a spectrometer as you said you were going to, just an FYI spectrometers cost a lot more than a few hundred dollars.

I don’t see anything that would make me think for two seconds there is gold in that spear point. Beyond normal microscopic background values that is. First rule of prospecting is learn what to look at, and what to simply ignore. The planet is full of stuff that looks like gold to people, but is not. I’m kind of amazed 5 pages has been spent on it. But hey, that’s what forums run on!
