Retgersite is a rare nickel sulphate mineral that typically forms in arid environments or as an alteration product of nickel-bearing minerals. It appears as delicate green to bluish-green crystalline crusts or powdery coatings with a vitreous to pearly lustre. Although little folklore surrounds Retgersite, its distinctive colour links it symbolically to renewal and vitality. Metaphysically, it is believed to promote emotional healing, balance, and adaptability. The stone is said to encourage growth, clarity, and a deeper connection to nature and inner harmony.
