Quartz Point
This specimen is a natural Quartz Point featuring a clear or milky body peppered with distinct black spots. In this variety, the quartz grew around tiny mineral inclusions—likely Hematite or Goethite—trapping them inside the crystal structure as it formed.
Without the overall orange or red staining typically found in "ferruginous" varieties, these points maintain a high-contrast, "salt and pepper" look. The black spots appear as sharp, organic specks or flakes suspended within the glassy hexagonal crystal.
Mineral Profile
The Core: Pure Silicon Dioxide ($SiO_2$). The crystal retains its classic six-sided shape and pointed termination.
The Spots: Typically metallic Hematite inclusions. While hematite can be red, it often appears jet-black when it forms as solid, unoxidized specks inside quartz.
Formation: These are known as included crystals. The black minerals were present in the hydrothermal fluids as the quartz was growing, causing the quartz to envelop them.
Hardness: 7 on the Mohs scale. The quartz is durable and scratch-resistant, protecting the softer mineral spots held inside.
Visuals
Clarity: The quartz ranges from transparent to translucent (milky), which provides a clean backdrop that makes the black inclusions pop.
Luster: The faces of the point have a bright, vitreous (glassy) shine.
Texture: While the inside looks "spotted," the exterior surface of the crystal remains smooth and polished by nature.
