Posnjakite is a rare copper sulfate mineral typically found in the oxidized zones of copper deposits. It forms vibrant blue to turquoise crystalline masses, often crusty or botryoidal, with a striking vitreous luster. Though not widely featured in folklore, its brilliant colour has long captivated collectors and mineral enthusiasts. Metaphysically, Posnjakite is believed to enhance clarity, intuition, and emotional balance, helping to release negative energy while fostering calm and insight. Its vivid blue hue also symbolises communication and spiritual awareness.
