40-50 million years ago

Each piece consists of multiple clusters of diamond calcite with high shine on a matrix of Limonite

or the formation of equally thin layers of secondary minerals due to hydrothermal or other alteration

Each of these pieces contain remarkable aquamarine crystal formations - some gem quality - for the true collector

it is not uncommon for insects and other small animals to become trapped within tree sap

Malachite, Fibrous Wulfenite and Mimetite 40-50 million years agoA vivid and richly colored copper based mineral, Malachite is known for its deep green coloration, resulting from the oxidation of its copper and sulfide components. Malachite has been mined for both use in copper tools and for ornamentation and jewelry. It rarely occurs in crystal form but is often found in botryoidal or fibrous formations. The rich, silky and lustrous texture of these fibrous Malachite specimens from Congo combined with the
