A larger, more substantial Milpo fluorite showing a deeper blue-leaning tone, with visible internal boulangerite inclusions adding fine, thread-like detail throughout the crystal. The fluorite has gemmy translucency, allowing light to move through and highlight both the color zoning and internal structure.

The main crystal face shows natural surface etchings typical of this newer Milpo material, with a mix of lightly frosted and clearer areas.

Metallic associations such as geocronite, galena, and pyrite are present around the sides and base. The overall composition feels complete, with the fluorite remaining the clear focal point.

This is a more size-forward example with noticeable internal character, making it a strong display piece as well as an interesting inclusion specimen.
