Vivianite may be the most goth crystal on Earth with its eerie glow and graveyard origins

Vivianite is the most goth crystal on Earth. This beautiful mineral forms in places rich in decaying organic matter, such as ancient graves, old bones, peat bogs, and even submerged shipwrecks. Freshly unearthed Vivianite often starts out pale or colorless, but exposure to light slowly transforms it into deep shades of blue, indigo, and nearly black. The result looks like something a Victorian vampire would keep locked in a velvet-lined coffin.

Part of what makes Vivianite so cool is how dramatic its transformation can be. The crystals can appear ghostly white underground for centuries before suddenly turning electric blue once exposed to air and sunlight. Photos of the mineral make it easy to understand why collectors obsess over it. 

Vivianite has been found directly on human remains, including bones, skin, and bodies preserved in unusual burial conditions. This crystal is the literal embodiment of something having a "silver lining". Vivianite's gloomy reputation, concentrated with its stunning appearance, is a big part of its allure to crystal enthusiasts.
