City of bismuth under glass
PUMI2084-3
This glass display on black stand makes you want to dive into this construction obtained by man, but from a natural ore, not concentrated enough in nature to see such crystals: Bismuth. A crystal achieved by heating up to 270 Celcius degrees some bismuth ore and waiting that they slowly grow with this crazy shape, cooling down.A bit like an Inca city. This is a remarkable size of crystalisation of this metal.
