Chalcocite - Sweden

£1.50 – £12.00 ex VAT
Green Opal

Opal (Green) - Indonesia

£4.00 – £12.00 ex VAT

£2.25 – £8.00 ex VAT

Specimens of stromatolite, collected from Bolivia. Stromatolites are a term used to describe a range of layered sedimentary formations, predominantly created by photosynthesising microorganisms. Fossilised stromatolites are crucial as they record some of the most ancient life. Stromatolites are created in shallow water environments, where sedimentary grains are trapped, binded and cemented in biofilms through the action of microbial lifeforms. Stromatolites can exhibit a range of different patterns and structures. These specimens are available in three sizes and come supplied in a white card tray with information label.

Puddingstone
Puddingstone Conglomerate £1.50 – £6.00 ex VAT

Specimens of Puddingstone, collected from Hertfordshire, UK. Puddingstone is a variation of conglomerate, which is term used to describe a coarse grained sedimentary rock, featuring large, well rounded clasts in a finer grained matrix. It dates back to the Paleocene to Eocene period around 56 millions years ago. This particular rock is composed almost entirely of silica and has no porosity, likely contributing to its notorious hardness. This rare rock is only found in quantity at one locality in Hertfordshire. As such, it is becoming exceedingly difficult to obtain. This rock is available in multiple sizes and each piece comes supplied in a white card tray with information label.

Bytownite Basalt £2.25 – £6.00 ex VAT

Bytownite basalt ( Bytownite feldspar) is another variation of the common Basalt rock. Basalt tends to to be a dark, fine, crystalline igneous rock and has a number of different variations. Bytownite feldspar is a calcium rich member of the Plagioclase family. The mineral was first described in 1835 & named for Bytown (now Ottowa) where it was found in Canada. High quality transparent examples are used to make faceted stone in the jewelllery trade. In these examples the phenocrysts are green & opaque & set in a basalt matrix. The specimens come from Cumbria, UK and are supplied in a white card tray with a label.

We also supply Bytownite Basalt thin sections for microscope study which are available to buy HERE.

Biotite Muscovite Granite £2.25 – £6.00 ex VAT

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.

Snowflake Obsidian
Obsidian (Snowflake) £2.50 – £8.00 ex VAT

Snowflake obsidian is quite striking in appearance. It is characterised by the inclusion of radially clustered crystals of cristobalite, which when viewed at a glance, appear like snowflakes on the surface of the rock. These crystal clusters are set in an otherwise black vitreous matrix of obsidian, which is an naturally occurring volcanic glass, even exhibiting a conchoidal fracture. Cristobalite is a high temperature polymorph of silica, it can form as a result of the devitrification of the obsidian. These specimens come from Java, Indonesia and are supplied in card trays, sizes which are optional, each tray also has a small data label supplied.

Aeolian Sandstone
Aeolian Sandstone £2.25 – £6.00 ex VAT

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.
