The scarey-looking but diamond-encrusted platinum cast humanskull is made by British artist Damien Hirst. When asking how much, you probably can't afford. It has a price tag of US$98 million.
The skull, named "For the Love of God", cast from a 35-year-old 18th-century European male, is coated with 8,601 diamonds, including a large pink diamond worth more than $8 million in the center of its forehead. Link
