Found this picture at the flea market, liked, not enough to buy but thought I'd find it online and share.
A bit more detail...
And a couple more I found from the same area and era...

So of course I'm playing with my new digital microscope and you have to bear the burden of my findings. Below, a perfectly shaped minute quartz point. Sure looks like a diamond, but it probably isn't.
That said, if you looked at the previous pebbles I posted, there's a big grey area...lots of things you can say definitely aren't, but there's a few I'm unsure about.

Now, playing again with the digital camera and some hydrochloric acid, I've put some of the previously photographed "pebbles" (more grit and grains of sand) in the HCL solution to see which dissolve and which survive. Those that survive - intact - are presumably diamonds...
This is the starting photograph:
You can see the bubbles as the HCL works it's magic. I spilled a bit, always, hopefully the desk and computer are here in the morning, but a time-lapse animation/.gif/vine will help to show me where to steer my attentions...In the past, I never knew which ones "survived" and which ones merely shrunk, and needed more acid to disappear. Now I'll know...
