yes
Pure boron (a metalloid) is not found in nature. Boron will be combined with something else. Pure boron could be shiny, but will usually be a brown powder when combined with carbon.

pure substance, propanone
The "pure element form" of boron is a meteorite. Boron isn't very reactive...but since it's formed by cosmic rays it isn't very abundant either.
