Chrome Alum Crystal Gemmy Specimen 2

£44.99

Chrome Alum specimen 109g 66:52:47mm. Gemmy and rare specimen, I’ve only found one other seller selling 1 piece on selling platforms. Chrome Alum is and it is lab grown (since the crystals are octahedral). Alum is water soluble, so it's grown by slowly evaporating or cooling a saturated solution of alum in water. It’s a beautiful example of what man can create based on the forces in nature.
