Help i.d. blue rock w/ many crystals,topaz

[sorryucantseeme]

While prospecting for gold ,I moved a 1000lb rock underneath it in a area about 2 ft in diameter there is no more black sand just this blue clay ,crystals, I took a clear stone to a jeweler and they told me it was a topaz spinel. Here are a few pix of what i found. Is there any chance of diamonds ? I have a microscope 75x is there any trick to determine diamond..I look at the lattice but the lady told me it was topaz.

sorryucantseeme great find. Check out the crystal i found and posted yesterday and the stuff on it looks like yours and topaz would be great. No one has identified mine yet. Happy hunting and thanks for posting.

Your first picture is a bit blurry and not very detailed. Try getting closer, like those latter ones.

A lot of what you see is quartz, a very common mineral. Often has a glassy to greasy looking surface.
