quartz and gold

Hi everyone. Found this rock on the beach eastbourne england. It weighs 117gr heavy for its size ,reacts to a magnet but when you use a smaller magnet it hasn't got the same force all over. As in the pictures showen it seems to have gold which while testing under a mug on the ceramic it leaves...

Hi all, help me identifying this Red rock found in my site in South India . Majority of the site has an outcrop of Quartz Feldspar of high Grade. Just wondering if this can be of any help to market this? Does it have any potential mineral that can be processed and used ? Thanks in advance.

I been going through my buckets of rocks that I collected over the summer, I found this one rock that seem's to have specks of gold, I don't know if it's fools gold or real gold. I want to crush the rock and pan it out, but I am not that good at panning.
