Black obsidian

Obsidian is the stone of clarity, it can help you see the truth in a situation that is clouded with misinformation, while also protecting your energy from being effected by negative energies around you.

It keeps you grounded to the hear and now, feet fully planted in the now and not the past or the future. It can also help you to stay strong and confident and true to yourself. 

It can also help you heal and clear emotional blockages or difficulties, and give you some emotional and spiritual relief.
