Mixed Mineral Specimen with Quartz and Green Mineral

This specimen appears to be a natural mineral formation, likely a crystal cluster or crystals embedded within a matrix rock. The primary matrix rock is a coarse-grained igneous or metamorphic rock, possibly a pegmatite or granite, characterized by its light brownish-pink to tan color and visible granular texture. Within this matrix, several distinct mineral components are observed. The most prominent is a large, translucent to semi-transparent crystal with a grayish-brown hue, exhibiting irregular crystal faces, suggesting it might be smoky quartz or a similar variety. Its size dominates the central portion of the specimen. To the left side of the matrix, a smaller, vibrant greenish-blue mineral chunk is visible, which could be amazonite (a blue-green microcline feldspar), beryl (aquamarine variety), or a copper-bearing mineral, providing a striking color contrast against the pale matrix. Additionally, scattered throughout the matrix, particularly at the top, are small, dark, elongated to anhedral crystals, possibly tourmaline (schorl), biotite, or hornblende. The overall construction appears natural and unpolished, showcasing a raw, 'as-found' state. There are no visible signs of repair or significant damage beyond natural weathering or fracturing that could occur during extraction. The crystal surfaces may show minor abrasions or inclusions typical of natural formations. The specimen's estimated size would be in the range of a few inches across, based on its appearance resting on what seems to be a piece of furniture. The quality indicates a typical study or display specimen for mineral enthusiasts, showcasing multiple minerals in association.
