About this specimen

Marvel at the stunning interplay of the shimmering mica and the crisp aquamarine inclusions within the Xuebaoding cassiterite crystal. This exquisite specimen, sourced from the renowned Xuebaoding mountains in Sichuan, China, offers a captivating display perfect for mineral enthusiasts and collectors alike.

Cassiterite (SnO₂) crystallizes in the tetragonal system and typically exhibits a high luster with a submetallic to adamantine sheen. This specimen features a well-formed cassiterite crystal with a rich, deep brown to nearly black coloration, contrasted by lustrous, flaky mica and translucent blue aquamarine highlights embedded within the matrix. The aquamarine, a variety of beryl, adds a subtle yet striking tonal contrast with its pale blue to greenish-blue hues and vitreous luster. Both minerals display excellent crystallinity, with cassiterite showing sharp, distinct crystal faces and aquamarine presenting transparent to translucent clarity.

The Xuebaoding locality is known for producing rare and high-quality mineral specimens, particularly cassiterite clusters associated with mica and aquamarine, making this example a sought-after addition for collectors interested in geological diversity and display quality. The specimen’s combination of crystal forms and color contrasts enhances its aesthetic appeal and scientific interest.

With a Mohs hardness of 6 to 7 for cassiterite and 7.5 to 8 for aquamarine, this piece is relatively durable but should be handled with care to preserve its delicate crystal edges and mica layers. It is best displayed away from direct sunlight and excessive moisture to maintain its natural luster and coloration over time.
