Nice collection TeAra
I see
First pic. Garnet, pyrope (rounded one) and almandine (cubic one)
Second pic. Possibly lazurite. How hard is the blue?
Third pic, Give us more to work with on the green stone. Can you tell how hard it is? The last pic you sent it looks very rounded. Does it have any noticeable crystal shape. Streak? Gonna withhold judgement until I know more but it doesn't look like emerald.
Fourth pic. Garlic smell is an identifier for arsenic.
Fifth pic. Can't tell from picture. Possibly some kind of ore with amethyst. How hard is the pink area? Can you get us a pic of just one rock, as close as possible.
Sixth. Obsidian
Seventh, feldspar.
Eighth, can see the green but nothing else.
Second batch of pics.
first pic, several things in that rock. Looks like quartz and ?calcite? How hard are the milk white crystals?
second pic. Now that is an emerald. Looks exactly like the one in my hardness test kit.
Third pic, This why I say it is not emerald. That stone is too rounded. Epiodot, green tourquoise?
Fourth pic, Really hard, corundom (ruby).
Fifth pic. Hardness test please. Also looks like emerald.
