Also called Millennium Spirit Quartz. Silicon Dioxide. Hardness 7. Beautiful quartz crystal points, sometimes in twins, that are almost completely covered by a secondary growth/formation of small crystals.
On most of these specimens the hosts crystal is sticking up out of the top of the formation.
Most of these specimens are a light purple color which is amethyst.
Some are a yellowish color, or citrine, and some are a whitish which is a milky quartz.
Some specimens are a combination of purple and yellow. Very unusual. These beautiful crystals were first discovered in 2002 in Africa and were named "Spirit" crystals by the local tribes that discovered them.
Quartz is the second most common mineral in the earth's
crust. Quartz is a silicon dioxide. If you were to take the metal
silicon, plus oxygen, plus a little time and pressure - you'd get a
quartz crystals. Quartz is 7 on the Mohs hardness scale, harder than
a steel knife blade.
Quartz belongs to the rhombohedral
crystal system. Quartz crystals are a six-sided prism terminating
with a six -sided pyramid at one end. In nature, quartz crystals
are often twinned, distorted, or so inter grown with adjacent
crystals of quartz or of other minerals as to only show part of
a individual crystals shape, these groupings of the quartz points
are called crystal clusters. Regardless of the shape or size of
a quartz crystal, it always has six sides. It's not uncommon for
the quartz crystals to have more than one stage or "growth" or
formation. In quartz crystals where there has been two or more
stages of formation unusual crystals are produced. There is the
crystal that forms to a certain stage and then later, silicon
dioxide forms a coating on the outside of the original crystal.
These specimens are called spirit quartz. Then there is the quartz
crystal where a crystal has formed and then a second stage of
growth/formation causes the silicon dioxide to form at the top
of the crystal, extending the length of the overall crystal. These
are called scepter quartz crystals. This type formation is some
times called phantom quartz crystal, where you can actually see
what looks like smaller crystal inside a larger quartz crystal.
Neat, huh! Then there are those quartz crystals that have inclusions
in them. This occurs during the formation stage. The most common
type of inclusions are water bubbles, called anhydrous, and the
quartz crystals with rutile inside that looks like hairs that
got caught in the formation stage.
Quartz crystals form in hydrothermal veins and pegmatites. Well
formed quartz crystals may reach several feet in length and weigh
literally hundreds of pounds. The Ouachita Mountains in western
Arkansas is often referred to as the Quartz Crystal Capitol of the
world. Beautiful super clear quartz crystals have been mined in the
Ouachita Mountains for industrial and commercial use for many
years. Mt. Ida, a small town in Arkansas, supplied clear quartz
crystals to the US Military be used in electronic equipment, such as
tanks, back during the second world war. These super-clear quartz
crystals are used today as "seed quartz" by laboratories in producing
quartz wafers used in all types electronics including watches and the
computer industry.
Quartz, in all its varieties has a conchoidal type fracture, or a
cone shape type fracture. Early man took note of this fact thousands
of years ago and learned to shape quartz type rocks in many different
shapes. Early man made stone knives, spear points, arrowheads,
scraper stones, drill stones, and a host of other items. Early man
found that with the use on quartz stones, they could shape the
stones, through flaking the stones, and could gather their food,
build their lodges with animal skins, make scrapers to clean animal
skins to be used as clothing and many other uses. It's a fact that
the human race advanced as rapidly as it did through man learning to
use stones, altered into many different shapes for tools and weapons.
Quartz goes by many names: Chalcedony, Agate, Onyx, Jasper,
Aventurine, Tiger's Eye, Rock crystal, Amethyst, Citrine, Prasiolite,
Rose Quartz, Milk Quartz, Smoky Quartz, Morion, Carnelian, Chert, Flint.
