About this specimen
Quartz, a member of the trigonal crystal system, is well-known for its durability and clarity, boasting a Mohs hardness of 7. This prismatic dark quartz crystal from the Lanwen Mine in Yunnan, China, showcases subtle internal zoning that adds depth and interest to its smoky, almost translucent coloration. Its vitreous luster highlights well-defined crystal faces, emphasizing the natural prismatic form typical of quartz specimens from this region.
The Lanwen Mine, located in Yunnan province, is recognized for producing fine quartz crystals with distinctive dark tones, often sought after by collectors for their unique aesthetic and locality provenance. This specimen’s subtle zoning—a variation in color or transparency within the crystal—enhances its visual complexity, making it an appealing addition to any mineral collection focused on Chinese minerals or crystallized quartz.
As a collectible display piece, this quartz offers both mineralogical significance and decorative appeal. Its rarity lies in the combination of its coloration, zoning, and well-preserved prismatic form, which together underscore the natural artistry of quartz formation. When handling, it is advisable to avoid exposure to harsh chemicals or prolonged direct sunlight to preserve its color and structural integrity.
