I have recently become passionate about rocks, minerals and semi precious stones, found in many of the rivers and lakes where I live, in the Laurentian area of Quebec. I found this rock in a little river which is in close proximity to an old "china" clay mine, in which I have found numerous odd stones.

But this rock is one of its kind. Creamy beige and slightly orange in color, with a smooth but bumpy texture. Very heavy, does not scratch easily and is full of quartz crystals, and perhaps other minerals, that appear to have clean break lines. It retains heat or cold for long periods of time and sparkles in its tiny crevices in the sunlight. I was wondering what type of rock is hosting these quartz crystals?

It looks like a piece of quartz to me.
