Gaspeite Gemstone Information

About Gaspeite - History and Introduction

Gaspeite is considered to be one of the newer gemstones on the market. It was named after the Gaspé Peninsula of Quebec, Canada; the location of where it was first described and discovered in 1977. The discovery of gaspeite is credited to renowned American mineralogists, D.W. Kohls and J.L. Rodda.

Gaspeite is an extremely rare nickel carbonate mineral, which belongs to the calcite group of minerals. Initially, it was discarded as a worthless byproduct of nickel sulfide mining. Most gem-quality specimens available today are sourced from Western Australia or New Mexico, USA. Gaspeite is typically pale green to bright apple-green in color, often accompanied by brownish veins of rock that run through the material at various depths. Gaspeite 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.

Identifying Gaspeite Back to Top

Gaspeite is a nickel magnesium iron carbonate and can be identified by its carbonate composition. Gaspeite belongs to a group of related isomorphous carbonate minerals that share many physical qualities. Gaspeite is quite dense with a specific gravity roughly the same as garnet. Its hardness is similar to that of apatite, ranging between 4.5 and 5 on the Mohs scale. Gaspeite exhibits perfect cleavage in 3 directions and can often be distinguished by its bright apple green color, brownish veiny inclusions and dull to vitreous luster.

Gaspeite is a member of the calcite group of minerals, which includes several other carbonates with similar physical aspects, of which calcite is the most well-known. Most calcite matter does not form with clean, transparent gem-quality material, thus the lack of gemstone value. There are not many related gemstones on the market today, although there are many that are similar in appearance.

Most Popular Similar Gemstones:

Chrysoprase, calcite, chrysocolla, jade, malachite and turquoise are some of the more popular similar gemstones.

Lesser-Known Similar Gemstones:

Serpentine, variscite and verdite are lesser-known similar gemstones.

Gaspeite Jewelry Ideas Back to Top

Gaspeite is a not a well-known gemstone and is most often cut into cabochons and beads for jewelry, or cut and polished for collectors only. Its rarity makes it a gem that will not be found in local jewelry stores. 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 in beaded jewelry or set in pins or pendants. Since the more recent discovery of a large gaspeite deposit in Australia, it has become more widely used for beads, bracelets, necklaces and carved ornamental objects. It is often set into silver designs, alongside many other popular gems like turquoise, chrysoprase, malachite, sugilite and lapis lazuli.

Note: Buy colored gemstones by size and not by carat weight. Colored stones vary in size-to-weight ratio. Some stones are larger and others are smaller than diamond by weight in comparison.

Gaspeite: Care and Cleaning Back to Top

How to clean your gemstonesGaspeite gemstones are rather fragile compared to most gemstones. Care for gaspeite should be similar to that of softer gemstones like apatite or opal. Since it is considerably softer than quartz, simply wiping off dust can eventually cause reduced polish and surface scratches. As with most colored gemstones, avoid ultrasonic cleaners and steamers. Do not use bleach or any harsh household chemicals or cleaners. You can clean gaspeite using soapy water and a soft cloth. Be sure to rinse well with warm water to remove soapy residue.

Avoid wearing gaspeite jewelry when engaging in vigorous physical activity, such as exercise, sports or household chores. When storing gaspeite, wrap it in a soft cloth or place it in a fabric-lined box. Always store gems separately.
