Augite andesite igneous rock specimens from Thirlmere, Cumbria, UK which are of late Ordovician age which form part of the Barrowdale volcanic group. The samples are of intermediate composition and contain phenocrysts of the pyroxene mineral, augite, giving the normally dark blue rock a black speckled appearance. The samples are available in 3 sizes and come supplied in a card tray with a label.

Augite andesite is a variant of the fine grained igneous rock, andesite which contains coarse grained phenocrysts of augite crystals. An extrusive rock of intermediate composition, containing between 50 to 63% of silica, the samples have a dark colour with a blue tint while the augite crystals provide a speckled black appearance. The rock is estimated to have formed during the late Ordovician period and forms part of the Barrowdale volcanic group with other rocks such as dacite and basalt also being present in the area as part of a pre-caldera formation. The rock is slightly denser than our regular line of andesite due to the added pyroxene crystals of augite as phenocrysts. Ideal for established collections and higher level education to exhibit the presence of phenocrysts in igneous material, the rock samples come from Thirlmere, Cumbria, UK and are available in 3 sizes and come supplied in a card tray with a label.

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.

Massive Biotite Mica specimens, collected from Arendal, Norway. These specimens depict a “massive” crystal structure, as opposed to the more commonly seen sheets. Like all biotite mica, these specimens are dark in colour, exhibiting a dark grey to black hue. Mica is one of the most common mineral groups, with biotite being the most abundant member. Biotite is very common in igneous and metamorphic rocks, with the dark minerals in granites, pegmatites and gneiss often being due in some part to the presence of this black mica. This massive biotite are available in limited supply so we recommend you move fast if you wish to add a piece to your collection. Supplied in a white card tray with information label.
Mineral specimen sample cards, these cards are blank having spaces for you to write the ‘name’, and ‘locality’ of a rock specimen or specimens collected. Ideal for conducting field work or cataloging your collection. 73mm x 46mm.

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.
Accretionary lapilli tuff is an igneous pyroclastic rock, these samples come from Longsleddle, Cumbria in the UK and forms when hot ash and debris is ejected from as volcano. Some of this material is held together by moisture and once heavy enough, falls into the ash below forming small ‘spots’ within the material, creating a speckled rock. The samples are suitable both for young and serious collectors as well as educational use and are supplied in various sizes with a card tray and label.

elenite pencils are exquisite and captivating mineral formations that showcase the natural beauty of selenite, a form of gypsum. They exhibit a pristine translucence that allows light to pass through, creating a mesmerising glow when held to the light. Each selenite pencil measures approximately 14cm in height and 4cm in width whilst being smooth and well weighted. This makes them easy to hold whilst remaining promenant enough to stand out as a decorative piece. They all feature a flat, hexagonal base, making them easy to stand on a range of surfaces. Since these items are made from 100% natural selenite, it is common to expect some slight variance between each specimen, whether that be in shape, size or the occasional scratch. Despite this, these selenite pencils would make a great addition to any room, adding some flair and elegance.
