Friendly reminder: don’t leave your vivianite in direct sunlight
Vivianite is extremely light sensitive, which is part of what makes it so fascinating. Exposure to sunlight can cause its color to darken, fade, or shift over time as the mineral oxidizes. Those deep green tones collectors love are actually tied to an ongoing chemical change within the crystal itself.
Basically… your mineral collection has vampires in it 🖤
