Arsenopyrite with Quartz Crystal Cluster, Inner Mongolia
Size: 2.6 × 1.6 × 1.3 inches
Weight: 100 grams (approx. 3.53 oz)
Locality: Inner Mongolia, China
This striking raw mineral specimen features a stunning intergrowth of metallic arsenopyrite crystals with embedded quartz formations. The arsenopyrite displays a sharp, lustrous metallic silver sheen, with well-developed geometric faces and brilliant reflections that catch the light from every angle. The crystal terminations are clean and distinct, with subtle iridescent hues on some surfaces, adding further depth and character.
Nestled among the arsenopyrite is a matrix of quartz crystals—translucent and icy in appearance—offering a beautiful contrast between the dark metallic luster of arsenopyrite and the soft glow of natural quartz. The specimen is in excellent condition and is mounted for stability and easy display.
A highly collectible piece, this specimen is ideal for serious mineral collectors, crystal curators, or those who appreciate rare geological formations. Sourced directly from Inner Mongolia, this region is known for producing some of the most desirable arsenopyrite combinations in the mineral world. This piece exemplifies that quality with its dramatic aesthetics and mineralogical integrity.
