• Detail of a cluster of white crystals on the tip of the point, small double-terminated quartz crystals like rice grains.
  • Full view of the piece in slightly different lighting, showing the light color of the more translucent parts. The color deepens as the piece becomes opaque in the top third.
  • Full view of a long hedenbergite quartz point, well-formed with the base cleanly broken. It has a light greenish-gray color that deepens as the piece becomes more opaque closer to the tip. There is a cluster of white crystals near the tip.
  • A closer view of the top half of the point, sprinkled with small rice-like crystals that form a cluster near the point. The surface of the quartz appears dull.
  • Full view of another side of the piece, with some sprouting growth and small black spot inclusions just under the surface. There is a grainy sand-like textured phantom inside the top third of the point.
  • Full view of another side of the point, which has some white overgrowth on the bottom half. There is some sprouting growth on the side.
  • The point angled so the light goes through it, showing the top third of the point is near-opaque with hedenbergite inclusions. There is some white overgrowth on the bottom half of the face.
  • The point with light shining through it, highlighting opacity of the top third and the small black inclusions throughout. The tip of the point is lightly chipped and not intact
  • The point angled so that light reflects off the surface, highlighting a couple crystals of sprouting growth and small indentations on the surface of the quartz. The piece has a thin almost beveled edge between faces.
  • Detail of the base of the point with light reflecting off, highlighting a few sprouting growth crystals and speckles of inverted spots from former crystals. Small black spots are just under the surface, barely touching it and exposed at the surface.
  • Detail view of the tip of the point, with an almost dusty appearing surface luster. There are small quartz crystals sprinkled on the surface.
  • Scale image of the point on a measuring mat, showing it is nearly 4 inches long, inclusive of angled broken base

These quartz points are from HuangGangLiang, and commonly called Mongolian or Inner Mongolian quartz. When the primary inclusion is hedenbergite, enough to give the quartz a greenish tint, it is more appropriately called hedenbergite quartz. 

This isn't your typically shiny quartz crystal; the points have a matte luster with a sheen effect, producing a ghostly appearance. Broken ends reveal the first generation of growth was an icy clear colorless quartz. A second generation of growth occurred, depositing a layer of cloudy hedenbergite-included quartz. Hedenbergite is often green-to-olive-brown in color, and gives the quartz a dull green-ish gray hue. Some hedenbergite quartz like one this produce an odd grainy effect just under the surface at the tip. Inclusions make the point near-opaque with a gradient to translucent at the base.

The whitish cluster of rice-like crystals are small quartz crystals. There are more quartz crystals and sprouting growth forms spread across the surface. The small dark spheres included inside the crystal and dotting the surface may be goethite or hedenbergite, but on other specimens they have a near-metallic luster resembling pyrite. The spots also may simply be iron or chlorite!
