Olivine mineral specimens from Åheim, Norway, samples vary from granular to crystalline but all exhibit a bright olive green colouration. Collected by staff, olivine is a subsurface mineral which is unstable at the surface and weathers easily, making it rare. It may also contain the gemstone, peridot as well as kammererite. Available in various sizes and supplied in a card tray with an information label.

Olivine mineral specimens are highly sought after due to their rarity and vibrant, striking green colouration. Olivine is a mineral which often forms in the subsurface of the earths crust, for this reason, it is often unstable on the earths surface and thus weathers easily. The depth at which it forms also results in samples being quite dense for their size. It derives its name from it’s green colour which is a result of nickle and is found in mafic and ultra mafic igneous environments. When high quality crystals are found, they are known as peridot and are highly sought after as gemstones, as they can be cut, shaped and polished with drastic effects, enhancing the green colour further more. It has also been found on the surface of the moon, rocks collected from the Apollo 15 mission brought back samples of olivine basalt. Specimens may occasionally exhibit small amounts or peridot or a rare mineral, kammererite, however overall, samples supplied are granular or crystalline in texture and exhibit the typical bright olive green colour. Available in various sizes and supplied in card trays with an information label.

Dunite igneous rock specimens from the Gusdal olivine pit in Åheim, southern Norway. Composed of green olivine minerals with chromite and pyroxene crystals, the rock forms as intrusive igneous plutons in the earth mantle down to 400 km deep and displays a coarse texture and green colouration. Overall, the samples are fairly granular and weak due to their chemistry and form part of the basal gneiss complex of southern Norway. Ideal for various levels of collectors and for higher level education and research use, the samples are available in three sizes and come supplied in a card tray with an information label.
We also supply Dunite thin sections for microscope study which are available to buy HERE.
Essexite igneous rock specimens from Lanarkshire, Scotland, UK, also known as olivine or nepheline monzogabbro is an intrusive rock with mafic chemistry, composed of nepheline and plagioclase feldspar along with olivine, magnetite minerals as well as augite phenocrysts which exhibit euhedral crystal forms. The rock has a dense weight and overall dark colouration but attractive appearance. It is locally known as Crawfordjohns and was highly sought after as a high quality material to produce curling stones. These samples are excellent for young and older collectors as well as higher educational use, the pieces are available in three sizes and come supplied in a card tray with an information label.

Garnet peridotite igneous rock specimens found in the Gusdal Olivine Pit, Åheim, Norway is an ultra mafic rock which contains high pressure and temperature minerals such as olivine and garnet crystals. Exhibiting a green colouraiton with striking red spots, these samples were pushed up to the earths crust during the Caledonian orogeny during the Ordovician and Devonian period over 400 million years ago. The specimens are dense as expected and are ideal for children and serious collectors because of the colourful appearance as well as for higher educational use to describe deep mantle material as well as orogenic processes. The hand samples are available in various sizes and come supplied in a card tray with an information label.

Olivine dolerite igneous rock specimens from Clee Hill, Shropshire, UK, composed of pyroxene minerals such as augite and magnetite as well as plagioclase feldspar. The samples are fine grained and crystalline in texture with a dense weight and black colouration. Similar in appearance to gabbro and basalt, the rock samples are suitable for serious collectors or higher level education to explain the difference in chemistry and mineralogy of igneous rocks. The samples are available in three sizes and supplied in a card tray with an information label.
