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

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.
We also supply Snowflake Obsidian thin sections for microscope study which are available to buy HERE.
