Vivianite is a heart healing stone. The stone helps to remove that ache that makes you mistrust all your connections. The stone pairs well with other heart stones like Rose Quartz and Moldavite.
These stones are from Rosia Poeni, Romania - they came fastened to an acrylic stand, so just be aware of that when you order. The stands are basically glued on. They may be able to be carefully removed if you'd like. But they are set up to be a display piece.
