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 greenish gray hue. Some hedenbergite quartz like one this produce an odd grainy effect just under the surface near the tip. Inclusions make the point near-opaque in the top third but translucent below this.

The specimen has sprouting growth forms. It is sprinkled both with whitish rice-like quartz crystals, and imprints of crystals that have dissolved. 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!
