Description:

**Originally Listed At $250**

Likely East Asia, China & South America, Argentina, ca. millions of years ago. Two interesting and beautiful mineral and crystalline formations. A banded slab of rhodochrosite, polished on both sides -one side flat, the other slightly convex. The slab features gorgeous pink and white banding, with silvery black galena inclusions at the center. Galena (PbS) forms from lead-rich hydrothermal fluids moving through cracks in the rock. Also included is a prismatic stibnite crystal with a reflective, metallic luster and striated parallel growth lines. Stibnite crystals are relatively heavy compared to their size due to the high density of the mineral and its antimony composition. Size of stibnite: 5.25" L x 1" W (13.3 cm x 2.5 cm); rhodochrosite: 3.125" L x 2.25" W (7.9 cm x 5.7 cm); Riker case: 8" L x 6" W (20.3 cm x 15.2 cm)

Provenance: private Los Angeles, California, USA collection, acquired in the 1980s
