Hello @quadeera!
Megan gave you some great guesses- Iām no crystal identifying expert myself, so I will back her opinions 
It can be hard to tell through the computer screen, so you may want to also check the Crystal Identification Chart and this Crystal Picture Identifier 
As for Crystal Charging and Crystal Cleansing, you can find tips and advice in the following threads:
