Specimens of Frosterley Marble, collected from Harewood Quarry, Co. Durham in the UK. Frosterley Marble is not actually a marble, but rather a black limestone consisting of Carboniferous age fossil corals. This makes it a sedimentary rock. The most famous use of Frosterley Marble is in Durham Cathedral where the ceiling of the Ceiling of the Chapel of Nine Altars has slender column supports composed from this stone. These specimens are available in multiple sizes and come supplied in a white card tray with an information label.

Limestone, a common sedimentary rock often used in building and stone work. These samples are carboniferous in age and are supplied by weight in lots of 1 kg.
Carboniferous coral limestone from Anglesey, North Wales. Composed largely of well preserved Lithostrotion corals, supplied in lots of 1 kilogram.
Lower Carboniferous crinoidal limestone from Derbyshire, U.K. Supplie dby weight in lots of 1 kg. Comes in a polythene bag with an information label.
Specimens of Cannonball Limestone, collected from around the Hartlepool area, in the UK. This is a very distinctive and rare form of limestone known as Cannonball rock. It is part of the Rocker formation; a basin slope deposit which comprises part of the Zechstein Group. This is a highly studied sedimentary formation which dates to the Mid to Late Permian Period. These specimens are small, and come supplied in a 1.5″ x 1.5″ plastic magnifier box with an information label.

Specimens of Oolitic Limestone, collected from Gloucestershire in the UK. Oolitic Limestone is a carbonate rock, that consists mostly of ooliths (or ooids). These are sand-sized carbonate particles (0.25 -2.0mm) built up of concentric shells of precipitated calcium carbonate (CaCO3). These layers form around sand grains or shell fragments that roll around on a shallow sub tropical sea floor, gathering layers of carbonate. Around the Cotswold Hills, the honey coloured stone has been the favoured building material for centuries. Many local picturesque hamlets showcase this. These specimens tend to be a little more friable than the examples from Yorkshire. These specimens are Mid Jurassic in age. They are available in multiple sizes and supplied in a white card tray with information label.
We also supply Oolitic Limestone thin sections for microscope study which are available to buy HERE.

Specimens of Limestone, collected from Derbyshire. Limestone is a common, well known sedimentary rock. It consists of the calcium-rich shells, bones, and skeletons of the fauna that dominated during that period. It was laid down approximately 350 million years ago in semi tropical seas and comes from the Dinantian epoch of the Lower Carboniferous. This rock is very pure, about 98% soluble in rainwater (over time) leaving only residual clay. Its uses include aggregate, building stone, the manufacture of cement, paper & calcium carbide. Available in various sizes, each piece comes supplied in a white card tray with information label.

Micro Granite is a variation of the granite group of rocks, composed of the minerals quartz, feldspar and mica. These particular samples were collected from Threlkeld quarry, Cumbria, UK. Specimens are supplied in a polythene bag in lots of 1 kg with a 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.
We also supply Syenite thin sections for microscope study which are available to buy HERE.
