Polycrystalline Silicon is a manmade material produced by refining silicon into multiple crystal grains, resulting in a metallic grey to bluish appearance with a crystalline, blocky texture. It is typically formed in irregular chunks with reflective surfaces.
Manufactured in the USA, this material is composed of high-purity silicon and is widely used in industrial and technological applications, particularly in semiconductors and solar energy production. It has a hardness of around 6.5–7 on the Mohs scale.
Each piece displays unique crystalline structures and surface patterns, making every specimen distinct.
