This is a natural quartz crystal with tourmaline inclusions from Karibib, Namibia, offered as an authentic mineral specimen for collectors.
The crystal displays a well-formed prismatic quartz habit with visible black tourmaline (schorl) inclusions enclosed within the crystal. The contrast between the clear quartz body and the dark tourmaline needles creates a strong visual and structural interest, highly appreciated by mineral collectors.
The specimen is completely natural and untreated. No polishing, dyeing, irradiation, or restoration has been applied. The crystal preserves its natural surfaces and internal growth features. All photographs show the exact specimen you will receive.
Quartz with tourmaline inclusions from Namibia is valued for its clarity, sharp crystal form, and well-defined inclusions, making it suitable for private collections, cabinet displays, and educational reference collections.
