Portland Stone is a variation of limestone which formed during the Tithonian stage of the Jurassic period. It has been quarried since the 14th century, notably on the Isle of Portland, Dorset. This pale rock is sufficiently hard to resist weathering but yet soft enough to carve hence it makes an ideal architectural material. It was famously used for the construction of St. Pauls Cathedral and Buckingham Palace in London. Like most limestone, Portland stone formed in sub-tropical seas where wave action even resulted in the micro oolites visible in some pieces. Specimens are supplied in a labelled card tray.
We also supply Portland Limestone thin sections for microscope study which are available to buy HERE.

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.

Gabbro igneous rock specimens from Balmedie quarry, Aberdeen, Scotland which exhibit a coars grained texture from the crystals. Formed as a mafic pluton intrusion, the samples contain pyroxenes such as augite along side plagioclase feldspar, amphibole and olivine crystals. They are derived from a body known as the Belhelvie basic intrusion which the parent unit being the Caledonian Supersuite. Samples exhibit a grey colouration and density and are suitable for the more serious or professional collector or higher educational use to differentiate similar looking igneous rocks with different compositions and origins. Available in three sizes, the specimens come supplied in a card tray with an information label.

Larvikite is an igneous plutonic rock and variant of monzonite from Larvik, Norway, due to its chemistry, it is composed mainly of orthoclase, albite and anorthite along with plagioclase which gives the rock a blue to silver shimmering effect. The igneous pluton formed during the Permian period, 292 – 298 million years ago during the the Variscan orogeny. A beautiful rock to observe due to its coarse crystalline texture and schiller effect, the samples are ideal for general interest, collectors and educational use with specimens being available in three sizes and come 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.

Graphic granite is an igneous pegmatite rock from Iveland, Norway, which forms in intrusive batholithic bodies that have a felsic composition. As such, the rock is mainly composed of quartz and orthoclase feldspar crystals and lacks any mica, making the rock leucocratic. These samples have what is known as a graphic texture, due to the formation of the crystals, which result in an appearance similar to that of cuneiform text which was once used by ancient human cultures. A brightly coloured, eye catching rock, the samples are suitable for collectors and educational use at higher levels and come available in three sizes. Each specimens is supplied in a card tray with an information label.

Diorite rock specimens from Cockermouth, Cumbria, is an intrusive igneous rock from the Ordovician period with a coarse, phaneratic texture composed of plagioclase feldspar, biotite mica as well as hornblende with intermediate chemistry. Found with the Skiddaw group, the rock samples are more suited for serious collectors and higher level education to describe the chemistry and mineralogy of various igneous groups. Available in 3 sizes and supplied in a card tray with an information label.

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.

Specimens of Aeolian Sandstone collected from Lazonby, near Penrith, Cumbria in the UK. This aeolian sandstone is Triassic in age – approximately 200 Ma. It belongs to the group of rocks known as the New Red Sandstone which date from the Permian (280 Ma) into the Triassic. The composition of this sandstone consists solely of spheroidal (millet seed) quartz grains with an iron oxide cement called haematite. It is the presence of this haematite that contributes to the distinct red – orange colouration of these samples. This lithology is typical of an aeolian (wind blown) hot desert environment. Available in multiple sizes, these specimens come supplied in a white card tray with information label.

Greisen metamorphic rock specimens from Caldbeck Fells, Cumbria, composed mainly of quartz and mica with an off yellow colouration. The rock is known as an endoskarn and forms when hydrothermal fluid and heat alter a granitic body, resulting a heavily altered rock which may contain trace amounts of rare elements. These samples are suitable for advanced collectors and higher level education and are available in three sizes, each pieces will come supplied in a card tray with a label.
