What’s your go-to Crystal and why?

Happy New Year Everyone! I’m curious, what’s everyone’s ’go-to’ crystal? that you use or wear everyday without fail, or most days? (I’m trying to broaden my knowledge and look for other crystals to use and wear).

For me, it’s a small piece of Blue Apatite which I wear in a necklace. It’s kept me motivated in what was a lousy past year, kept my spirits up and yes it does work as an appetite suppressant! It’s helped me quit sugar, quit alcohol…it’s a pretty miraculous crystal ☺️ But! I want to hear yours and the benefits. Please comment and help me expand my knowledge. I need to complete my PhD this year, so I’d love to find a crystal that can kick me up the ass for example 😂😂😂
