Would anyone be able to tell me what kind of stone this is? It looks to have smoky quartz pieces throughout it but I’m not 100% sure. Has anyone seen something like this before? Thanks in advance!

    $\begingroup$ I'm not sure the geologists are going to be able to help a great deal, as parts of the picture are out of focus... suggest putting it on table in a well lit area and taking a variety of careful pictures. Additionally, including the information found in the answer here would greatly help in the potential for good answers :) $\endgroup$ – JeopardyTempest Apr 9 '18 at 2:54

    $\begingroup$ What color is it? Tan with darker inclusions that look like Smokey Quartz. What kind of lustre does it have? Pearly in sunlight. Is it made up of layers? I can’t tell for sure but it looks to possibly have layers. Can you see grains? No How easy is it to break pieces off? Not easy at all. How homogeneous is it? It seems to be a composite. Maybe quartzite and Smokey Quartz. Does it seem unusually light or heavy for its size? It has weight but is not overly heavy for the size. I will try to test mohs tomorrow. $\endgroup$ – Shawna Apr 9 '18 at 4:52

It appears to be plagioclase feldspar, the white part of the sample, with smokey quartz inclusions. This is a igneous rock. See if a knife can scratch the dark mineral, if it cant its most likely quartz which is common in this type of rock. Look close at the dark material is it glassy if it is then most likely it qaurtz.

    $\begingroup$ Even though the pictures are terrible, I agree with this answer. It's probably a feldspar (not sure whether it's plagioclase or not), and quartz. In short, it's a granite (and a nice one too). $\endgroup$ – Gimelist Apr 10 '18 at 8:19
