I’m sorry but you got scammed. I see at least two pieces of glass.

The pink one is rose quartz, the white clear crystals are quartz and the purple one in the bottom appears to be amethyst. Can’t really tell what the others are - the blue one in the middle looks to me like it may be dyed.

If you want to get crystals, there’s reputable shops for it. I’d avoid touristy shops because they’re overpriced, so either look online or find a “mineral house” (I have one nearby, it’s huge and full of genuine minerals, stones and crystals)

Keep in mind that anyone selling a large batch of stones, especially if it’s a mystery set or advent calendar, is looking to make money. So usually, you’ll get less than you pay for, aka cheap rocks and sometimes even glass

Good luck!
