I am usually great on spotting fakes but I honestly cannot tell

I purchased this Blue Apatite from someone on Etsy, I was feeling pulled to get some Blue Apatite. They contacted me, told me I was their first sale, that they were nervous about the shipping and to please let them know when it arrived and if it was okay. I got it today, I was so excited to see it but when I opened it, it wasn’t at all what I expected. I’ve seen Blue Apatite, I have some tumbled stones but this feels off to me. I think it’s real but something feels off- is it just the vibe on the crystal or is it fake? Need help.
