description Gaspeite Overview
Gaspeite is a rare nickel carbonate mineral with the chemical formula (Ni,Fe,Mg)CO3, first described from the Gaspé Peninsula in Quebec, Canada. It typically occurs as bright apple-green to yellowish-green masses and is found in the oxidized zones of nickel sulfide deposits. Notable sources include Western Australia and localities in Canada. Its distinctive color makes it popular among mineral collectors, and it is occasionally cut into cabochons or used in inlay jewelry.
help Gaspeite FAQ
Is gaspeite a rare gemstone?
Yes—it's a relatively rare nickel carbonate mineral, and jewelry-grade material is quite limited. Most gem gaspeite on the market comes from Western Australia, where it forms in the oxidized zones of nickel sulfide deposits, rather than from its Canadian type locality.
Why is gaspeite green?
Its bright apple-green to yellowish-green color comes from nickel in its chemical structure, (Ni,Fe,Mg)CO3. Higher iron content tends to shift specimens toward yellower or browner tones.
Where was gaspeite first discovered?
It was first described from nickel deposits on the Gaspé Peninsula in Quebec, Canada—the source of its name—in the 1960s. The Gaspé material defined the species even though Australia later became the main supplier for the gem trade.
How is gaspeite used in jewelry?
It's especially popular in Native American, particularly Zuni and Navajo, inlay work set in silver alongside turquoise and coral. With a Mohs hardness of only around 4.5 to 5, it's better suited to pendants, earrings, and inlay than to rings that take daily knocks.
