Not to be rude about it but, rocks, several rocks of different colors. You can’t just post photos of 26 different stones and say what are all of these. It doesn’t work that way.
Where did you get them? They look like sapphires to me, guessing they-re from same lot. You can get an inexpensive gem tester on Ebay
Yes, they may look like colored rocks. But if I was to guess, I would say sapphire.
They look to me such as zircon, or apatite from a sand concentrate.
If you could please let us know where these stone were found. Were they mined or panned from a river bed? Thank you in advance.
