This is an awesome mineral. Vivianite is a rare, blue to green hydrated iron phosphate mineral.  It is said to symbolize compassion, emotional strength, and renewed hope.  We will gift you a membrane frame to keep it in.  These are very fragile and can splinter easily, so keeping them in these frames, you can display them without fear of breaking them. These crystals grow on things that have expired.  A word of caution: Do not keep this mineral in a sunny window. It will cause this to turn black.
