It turns black immediately when it touches flame (Is that a heat test?).. and scratching doesn't do much but reveal a bit more shiny silver coloring.. It is such an odd shape with worn down rounded surfaces.. didn't know lead looked like this!

Found this in New River, AZ, base of Gavilan Peak. The shiny areas are slightly magnetic. I am interested in learning the composition, and whether I should break up the rock and try to separate the crystals or if other tests are needed to determine if there is any value to this specimen. I am new to mineralogy and prospecting. Thank you for any feedback you can provide.

If that's a geofact, it's one of the more interesting I've seen lately. VERY interesting. Any tool marks to see? Stone anchor? Big side-up, ropes loop around in notches. I think you can make up any story you like as a conversation piece! Maybe try a Google Image search?
any ideas on this guy it looks like a tool of some sort.

Hello! This is my first post here - I appreciate the smart, friendly responses I've seen, so I figured I'd post my rock for identification. I've been building mountain bike trails on my land west of Boulder, Colorado. We have several mines / prospecting sites on the land, supposedly they were wolframite / tungsten lodes. Anyhow, I had to chip through a quartz-laden field and came across this unique rock. I've seen plenty of mica-quartz combos and plenty of milky quartz with red intrusions (iron?) but this one really sparkles. Any ideas? Thanks! Sorry I don't have a quarter for reference, this is a pretty big chunk, about the size of half-loaf of bread.

Welcome to the forum!
Disclaimer: I'm no rock expert.
1st thought is it's silver. Is the dark grey vein metallic? Has the appearance of natural silver too me in the image.
Kenmitch - thanks for the response, I appreciate it. I have a rare-earth magnet that doesn't stick, so it's not magnetic. You should see this thing sparkle in the sun, it's really quite beautiful. There are a few other rocks near where this one was found that look the same.
By crushing the rock to powder then pan it, after that you have to melt what you've paned out. Be careful not to breath anything in . . you will need to add some sort of powder to it to help separate the gold when you melt it. Its not really worth all the trouble unless you have a lot of material

Sup guys!
My friend and I had some awesome finds this weekend. I was wondering if the blue rock is an agate? Also on the nugget we dug - any idea of what the host rock is? We were thinking quartz or agate? Thanks a ton guys!!

As to the nugget...probably quartz. Agates are silicon based and so is quartz...that doesn't answer your question but a local rock shop might.
Nice find on the gold!
Good luck.

Thanks! We were super excited 
We're going to take it into the local smelter here in Portland next week when the guy gets back who can do the specific gravity test on it. Hopefully he knows. I'm just wondering if I should be picking up all this similar colored quartz/agate to start crushing it looking for gold....hahaha.

Don't know about picking up random pieces for crushing but if I were you I would take my metal detector for a ride and take home anything that sounds off even if it doesn't have a show of visible gold.

Rgr that.
Ya we're def on this area with the detectors - only made it there 3 times this year and now it'll be snowed in
. The goldbug 2 found that little 16 gram specimen. We know there's more out there it's just getting through the material.Beachcomber82

Found this on a beach in New England. Looks like different shades of quartz from dark to light. Thought the images are worth sharing.
