Hi All
New to this forum but not new to prospecting and gem hunting.
I have a piece of breccia that has a intrusive vein in it.
It has these clear stones that have fire in them, anyone recognize them.
I have panned the crushed material and the are heavy.
Paul

Hi Bluestonehunter and welcome.
The likelihood that your unknowns are diamonds is very, very, very unlikely.

If you are serious about continuing this pastime, perhaps it would be wise to invest in some tools which would make identification easier.

and a reliable digital carat scale to use with it:

You seem to suspect that a lot of your discoveries may be diamonds (re: pink diamond from another post, again, very, very, very, very, very, very unlikely).

Perhaps you should consider getting a thermal Presidium Diamond tester. It will identify rough, polished and mounted diamonds. Do not me tempted to get unit which claims to identify a number of gems. This includes passing on the Presidium Diamond/Moissanite tester. They are very, very, very, very, very, very unreliable. :D

I have never seen diamonds in a quartz (or feldspar) matrix as your pictures seem to show. So the likelihood of these being diamonds is pretty much nil. The petrology doesn't match.

Curious what you guys think of the heavy crystals on the edge of the material, this came from a breccia i crushed and panned.
