Formula: SiO2 (with trace elements & inclusions)
Origin: Africa, Democratic Republic of the Congo
A very unusual variety of Quartz originating from the Democratic Republic of the Congo. Cloudy, clear, citrine to smoky Quartz crystal clusters with various different inclusions and phantoms.
These crystals seems to have formed in many stages but three main stages can be distinguished (see photo below), opaque milky to light Amethyst coloured Quartz crystals on a Muscovite Mica containing base rock. Over these original crystals a ferugginous (Hematite) coating developed, after which secondary Quartz crystals and other minerals developed on the Hematite coating. Various mineral inclusions also developed at the same stage as the secondary crystals.
It is very unfortunate that the due respect was not given during the collecting and transportation of these specimens in this remote African country. Undamaged specimens of this rare Asylum Quartz is extremely rare and hard to find.
Mineral inclusions of Asylum Quartz
Some crystals clusters may either be plain, in some a few crystals may have inclusions or phantoms, and in others all of the crystals may have numerous inclusions or phantoms.
The most common feature of these specimens are beautiful red Hematite phantoms that can vary to dark brown and almost almost black.
Several crystals has an unknown golden-brown to darker brown rutile-like, possibly Amphibole or Epidote mineral inclusions.
Small clouds of green Chlorite inclusions is found in some specimens, often in association with the red Hematite phantoms.
In a few specimens globular red Hematite inclusions and/or globular black Hematite or Goethite inclusions can be found.
More rarely on the surface of the Hematite phantoms, unknown blue globular mineral inclusions, and an unknown mineral with tiny white radiating needle-like crystal structures can also be found.
