Try reading the sticky post on identifying first so run some tests yourself. That looks like a surface coating on quartz since its a useless source for anyone to help you. First help yourself and follow the guidelines posted to prevent useless posts like this. No reason to try to help if you won't make an effort yourself.

OK. actually i had read all your guidelines about running tests. As I had exhausted all of them, I decided to seek help here. Also, I work with the local geologists here, but they seem to identify everything with a shine as being quartz. It's a dead end, as my understanding is that feldspar is equally abundant as quartz on the planet, but all i get from geologists is "feldspar is opaque" and I check it out and lots of feldspar is NOT opaque but translucent.
There is a huge pile 60 metres X 10 metres X 3 metres deep of rocks. Some of them are definitely rose quartz, but others have a more peachy colour and look different. Others are white but with black tourmaline inclusions like this piece. It looks to me as though they have feldspar cleavage.
I would expect in a pegamatite in a granite region to find some quartz and some feldspars. There are literally hundreds of abandoned mines from the 40s where all they wanted was wolframite which was worth loads of money and this region is famous for it. So all the other rocks got left behind.
