Green Gaspeite Gemstone

Gaspeite is a rare gemstone ranging from grass-green to olive or yellowish green, often displaying brown veining. Initially found near Mount Albert in Gaspé Peninsula, Québec, Canada, most Gaspeite now originates from Australia. This gem is a nickel carbonate and belongs to the calcite group. It is commonly found alongside magnesite as an intermediate material. When the stone contains more magnesium, it is classified as magnesite, known as lemon magnesite in the industry. Conversely, if the material has a higher nickel content, it is identified as Gaspeite.

Gaspeite Rough Stone

Gaspeite is composed of nickel magnesium iron carbonate. Crystals of gaspeite are typically translucent, but the mineral is usually found in opaque massive form. Gaspeite is quite a dense material, with a specific gravity of 3.7, roughly the same as members of the garnet family. It has a hardness rating of 4.5 to 5 on the Mohs scale, similar to apatite. Gaspeite has perfect cleavage in 3 directions. Its luster is dull to vitreous.

Gaspeite Chrysoprase Necklace

Gaspeite was initially discarded as a worthless by-product of nickel sulfide mining, but it has been gaining popularity within the gemstone industry. This is partly due to its rarity and partly due to it resemblance to the rare green turquoise. It is often set in silver alongside gems such as turquoise, chrysoprase, malachite, sugilite and lapis lazuli.

Since gaspeite is a slightly soft gemstone, it is not recommended for rings unless well-protected by a bezel setting. You will most often see gaspeite set in pendants or pins, or in the form of beads.
