Found near Niland, California. Crystals formed in a pocket. Interesting stuff, thank you magnification. One whole rock, two pockets. Pics: 1 2 Complicated crystals structure so small I cannot discern what they are. Please help, I appreciate responses.

Possibly a beryl in a granite vug?

Is the rock for sure granite? Beryl can form hexagonal/tabular crystals I just read.

Most likely = 1. α-quartz crystallizes in the trigonal crystal system, six sides, but comes to three points. 2. β-quartz belongs to the hexagonal system, six sides and comes to six points. 3. Topaz Looks like flattened quartz crystals. 4. Beryl often has flat top, but sometimes has odd terminations.

Got on mindat.org and checked Imperial county's list of minerals... so definitely not baryl. Are these quartz crystals then?

Second image looks like white topaz to me. Could be an oddball quartz xl habit too.

In the dry pics is looked like a right angle termination... This is a horrible way to get this conclusion. Just because nobody else has recorded something in a remote area doesn't mean you can't. If you actually find Beryl in Imperial County, you won't believe its true, using this method.

I am still wondering what those crystals are. I think I know what they may be. Quartz, definitely, but what crystal structure? The host rock is clearly granite.
At the same time 1dave backs up his topaz theory. The crystals do have a flattened termination or head, what have you. I'm not familiar with topaz, sadly.
