All about the Rarest Mineral on Earth

"I conducted a study of the first sample. The results became the standard used to confirm further painite discoveries," Rossman says.
It was through this research that Rossman determined what elements makeup painite. Using infrared spectroscopy, infrared radiation is used to identify elements based on how they absorb, reflect, and emit that light.
With infrared spectroscopy, infrared radiation is used to identify elements based on how they absorb, reflect, and emit that light. With Raman spectroscopy, a laser is used to scatter visible, infrared, or ultraviolet light, which makes the molecules give off unique vibrations that make them identifiable.
Rossman also found there was an error in the chemical makeup originally determined by scientists at the British Museum. While they had correctly identified aluminum, boron, calcium, and oxygen, the element zirconium was missing. Another thing Rossman found out was what gave painite its reddish hue; It has trace amounts of vanadium and chromium that might make it deceptively appear like a ruby.
