Whether it be confronting childhood trauma or revisiting the pain from a past toxic relationship, Mercury retrograde is a great time to look back and heal the wounds of the past. Bahri says turquoise is a fitting crystal for this work because it "reminds us that even the darker parts of ourselves and our past are an important part of who we are today." If you find this applies to you and your Mercury retrograde experience, try meditating on that healing with a piece of turquoise.
