Beryl is the parent stone of emerald and aquamarine, and old lore used it for seeing clearly. Dream books read it as insight, honesty and a family of gifts sharing one root.
Does the traditional reading fit your dream, or did it mean something else to you?
My Cosmic Code has a private dream journal. Write a dream down and the app picks out the symbols in it, shows what dream books say about them and, over time, which words recur across your entries. The journal is stored on your device only.
