Here's a substantial single fluorite crystal from the Milpo Mine in Peru that features a strong modified octahedral form, heavily etched natural surfaces and an extraordinary density of dark inclusions suspended throughout the interior.

The crystal is incredibly complex for its relatively simple external shape. The crystal faces are beautifully etched, featuring stepped growth and irregular surface textures. Internally the fluorite is packed with dark mineral inclusions, the most striking of which are fine needle growth that is consistent with boulangerite, an association that has appeared in more recent Milpo material. Galena is also present, adding darker metallic areas around the crystal and internally. Recent Milpo specimens with boulangerite inclusions are being specifically noted as a newer feature from the locality.

Several stationary fluid bubbles are visible within the fluorite. They don't move freely like classic mobile enhydros, but they add another layer of internal detail to an already feature filled crystal. Under strong light, the body transforms from pale sea green through deeper internal zones, allowing the inclusions to become increasingly visible as the crystal is turned. The inclusions also show up spectacularly in natural daylight, where they shine like glitter suspended within.
