Featured jewellery i don't wear, what are the name of the stones?

dear all

edit: jewellery i will never wear ..

"red and orange and yellow, green, blue and purple too. i can sing a rainbow, sing a rainbow, sing a rainbow tune." missing the blue, the green was posted already
then there's black or dark whatever ...
the yellow stone has a chip
there is garnet and sapphire and onyx and pearl
.... and tiny real or larger fake diamonds

i'm going to pierce my ears for photo...4 & 6

 

The yellow stone with the conchoidal fracture is quartz.

 

so 3, 4, and 5 are garnet, onyx and quartz. the last photo is pearl and sapphire. will offer these to my cousins before i put them up for sale

 

#4 is blue and not onyx

 

it looked black to me but i will check it again

 

those better be some nice cousins......!!

 

I was thinking sapphire .....but it's hard to tell from just a photo......
