The discovery of gaspeite is credited to renowned American mineralogists, D.W. Kohls and J.L. Rodda. Initially, it was discarded as a worthless byproduct of nickel sulfide mining.

Gaspeite is considered to be one of the newer gemstones on the market, it has recently become very popular among gem and mineral collectors, mostly credited to its rarity and its slight similarity in appearance to rare green turquoise. Gaspeite is typically pale green to yellowish-green to bright apple-green in color, often accompanied by brownish veins of rock that run through the material at various depths. Gaspeite crystals are typically translucent, but when found in its natural state, gaspeite is opaque.
