Identity HelpWhat The Heck Is This? Weird Looking Double Sided Mixed Minerals

Hi everyone. Hope you are all doing well. I am not an advanced collector and really know very little about minerals. I am in Coronavirus lock down here on Long Island, New York and am bored out of my mind. I thought I would try to identify all the minerals in my collection that miff me just to pass the time.

I have made a PINTEREST Photo Album showing these mixed minerals with 31 photos showing this weird looking specimen I have. I will add a few photos here, but if you can please click on the link to see every single detail:


About 4 years ago I purchased this mineral and the seller was a Chinese mineral dealer that shipped me this mineral and it came all the way from China to me in the USA. He did not say what the mineral was or where it was from. I think they do that so others can't find their claim or some other reason like that. I liked it because it was weird looking. It has different minerals on two different sides. One side has what appears to be very black looking quartz on a bed of some kind of pink feldspar, albite, microcline or orthoclase(?). There is some green colored minerals on some of the black quartz. 

The other side is my favorite because it is so sparkly. I thought the little crystals were quartz, but the shapes on the tips are weird and geometrical. There are larger peachy colored geometrical shaped minerals on top of the beds of smaller crystals. Some of them look twinned if that is the correct term. I affectionately named this mineral specimen a "Franken Mineral", lol. There are also other tiny little minerals throughout the piece. 

Can anyone tell me what the mixed minerals are and a possible location? Thanks in advance for all of your replies. Stay safe out there.

Your specimen is very likely from this location: 
https://www.mindat.org/loc-216835.html and likely more specifically this location within that county, which appears to be a massive quarry: https://www.mindat.org/loc-217594.html

You are correct that you have Smoky Quartz with pink feldspar on one side, which is likely Microcline, these look like they were from a pegmatite deposit or a miarolitic cavity. The green mineral coating the others is likely tiny crystals of Epidote (I am basing that totally on association, I can't make out enough detail from the photos, and it is reported from this location). The most striking feature of your specimen is the fact you have what appear to be a bunch of well formed crystals of Calcite associated with the Smoky Quartz and Feldspar, which is a rather uncommon association for pegmatites and miarolitic cavities. Although there are no photos of pieces with both Calcite and Smoky Quartz from this location on mindat, there are photos of similar looking Calcite on the same feldspar matrix.

Ian! Holy cow you are amazing!! I am so thankful for all that information. As a matter of fact the location rings a bell to me as I am almost certain the return address label had the words Shandong on the address label on it when I got it. 

I think all of you who reply to mere amateurs like me teach us so much. It is so kind of you to take the time to help educate newbies like me and make this hobby so interesting and fun. Once again thank you from the bottom of my heart for helping me!
