My brain is fried from Suduko ..... I forgot something ...
The blue piece ..... we think is ....
Blue Quartz .... Raw ........... or
Blue Aventurine ..... or
Crystalline Kyanite ....
Are any of these correct?

The first one could be kyanite and the second is hard to tell. You are saying white but is there a little yellow to it? I have some yellow onyx that looks similar but I can't really be sure. Onyx and Kyanite are both soft.

The blue looks like kyanite. The white looks like marble . Was it a soft stone?

Looks like lapis. The metallic flecks are probably pyrite and that is characteristic of lapis. It might be included sodalite bu the pyrite would be unlikely in sodalite. kyanite is usually pretty splintery and full of fractures. It has very distinct cleavage and can be hard to work with- I base this on my one experience with it. The crystals are usually blade shaped and pretty distinctive, too. This looks pretty mottled in color and that also suggests lapis. I haven't a clue about the heart shaped piece.

the blue one looks a bit like labradorite to me, but kinda hard to tell from the photo.

I think it's apatite. Nice blue color. Lot's of fractures. I've got a few pieces but the fractures keep me from tumbling it. I've seen it polished and it's pretty. Ebay has some gem quality for sale at times.

CarlosCinco ....
You bring up a good point about hardness ...
This little thing seems to be pretty tough.....
Mind you if I smacked it with a chisel and hammer it would break.... but....when try to on other fronts break or crack it .... it is pretty solid
And .... originally when I got it ....it really looked like someone had painted nail polish on it ... SO .... what else could I do but apply nail polish remover.
I tried applying nail polish remover on different sections and the surface did not change.
Pretty little thing ..... but elusive to me ....
Thanks Again To All
