Specimens of Basalt, collected from Northern Ireland. Basalt is a common, extrusive igneous rock, that forms when magma erupts and cools quickly on the Earth’s surface. These specimens are part of the Antrim lava group and date to the Tertiary period, around 60 million years ago. This is the same as the Basalt that makes up the famous Giant’s Causeway. The chemistry of these specimens suggests that the rock is olivine basalt, and comprises plagioclase feldspar, olivine and augite. These specimens are available in multiple sizes and come in a white card tray with an information label.
We also supply Basalt thin sections for microscope study which are available to buy HERE.

Amygdaloidal basalt is an igneous rock which is extrusive in nature, these specimens formed over 60 million years ago during the Tertiary period and come from Ireland. They are part of the Antrim lava group and exhibit a dark colouration with occurrences of amygdales containing quartz and calcite crystals. As a basalt they are somewhat dense, but lighter than pure samples due to the cavities within them which formed as a result of gaseous activity during their ejection. Over time, hydrothermal fluids pass through the rock and minerals form within the cavities, which gives the usually dark coloured rock a speckled appearance. These samples are available in various sizes and are suitable for higher educational use to detail the subtle differences between similar igneous rocks, they come supplied in a card tray with an information label.

Introducing an outstanding triplet hand lens with a remarkable x 10 magnification and a wide 21 mm viewing field. This loupe enables detailed examination of specific areas within a sample. Crafted using three precision-ground glass elements (triplet optics), it delivers exceptionally clear vision. Additionally, this model features both LED and UV lighting options, making it an ideal tool for geologists and entomologists. In particular, for ex the fluorescent properties of minerals, crystals, and insects.
The lighting system consists of a ring of six bright white LEDs that enhance the visibility of your chosen sample. The single UV LED emits longwave fluorescence, causing many materials to emit a glowing effect in the dark.
Encased in durable plastic housing that seamlessly integrates with a stainless steel body, this loupe is powered by three LR297 button batteries (included). It comes with a key for easy battery replacement, and a leather case for added convenience. This versatile lens is an indispensable tool across various professions including geology, sedimentology, mineralogy, entomology, botany, jewelry making, gem cutting, and more
Biotite granite igneous rock specimens from Ballachulish, Scotland, UK. Composed of the felsic minerals quartz and feldspar, with occurrences of biotite crystals. The rock has an overall white appearance due to its felsic chemistry but the black biotite mica offers a striking contrast in colours. The samples are ideal for both collectors due to the attractive nature and for college to university level education to describe the variations in granite which one may find. The samples are available in three sizes and supplied in a card tray with an information label.

Biotite muscovite granite specimens from St. Austell in Cornwall, UK of Permian age is a coarse grained igneous rock composed of quartz, plagioclase feldspar, biotite and muscovite. The rock is part of the St. Austell pluton which formed 280 million years ago. An off white colour with gold and black flecks of micas, the rock has a unique chemistry and resulted in the rich mineralisation of ores in the area. The samples are suitable for collectors and educational use to show granite variants, available in three sizes. Each piece will come supplied in a card tray with an information label.
We also supply Biotite Muscovite Granite thin sections for microscope study which are available to buy HERE.

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.
The sedimentary rock texture card is made for earth science students, it displays numerous bites of information on how to determine an sedimentary rock specimen found in the field such as grain size, texture and an indication to the energy required to form the rock. The cards have been laminated, making them waterproof, small, the size of a bank card and an excellent to hand guide for students, amateurs and professionals.

A comprehensive table gives an overview of the colour, hardness, lustre, mineral habit, cleavage and fracture properties of the minerals pictured. Information on the field occurrence, formation and economic uses of minerals is also included. Clear colour illustrations and text by experts in the subject make these valuable resources for all age groups.

Brockram Breccia specimens sourced from Hoff, Cumbria, UK. Breccia, a type of clastic sedimentary rock, is characterized by its coarse-grained and poorly sorted nature, containing large angular fragments embedded in a finer-grained matrix.
Brockram is a basal breccia, composed of cemented limestone and sandstone fragments originating from the Permian period. The Permian was the last period of the Paleozoic era and occurred approximately 299 – 251 million years ago.
These samples are available in various sizes and are presented in a white card tray along with accompanying information label.
Specimens of Chrome Diopside that were collected from the Gusdal Olivine Pit, Åheim, Norway. These samples are best described as chrome bearing diopside. Diopside, a vivid green pyroxene mineral, features streaks of grey chromite that creates a stunning mineral sample that would be the perfect addition to any collection. Whilst many samples of chrome diopside tend to be crystalline in nature, our samples are unique as the feature a grainier, more crumbly texture. These specimens are in limited availability, so we recommend you move fast if you wish to add these stunning specimens to your collection. They are available in a range of sizes and come supplied in a white card tray with 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.
We also supply Garnet Peridotite thin sections for microscope study which are available to buy HERE.
