Natural specimens may vary slightly from the listed measurements.
This is a natural quartz crystal with phlogopite and aegirine inclusions, offered as an authentic collector mineral specimen.
The quartz crystal shows good transparency with clearly visible internal inclusions of phlogopite mica and aegirine, creating complex internal patterns and strong visual contrast. The inclusions appear as dark, platy and needle-like structures enclosed within the quartz, highlighting the crystal’s growth history.
Such multi-mineral inclusion quartz specimens are valued by collectors for their mineralogical interest, as they document simultaneous crystallization of different mineral species under evolving geological conditions.
The specimen is completely natural and untreated. No polishing, repair, or artificial enhancement has been applied. All photographs show the exact specimen you will receive.
Suitable for advanced mineral collections, cabinet displays, and educational reference collections.
