This Skeletal Amethyst crystal is a real treat , the base of the crystal is Clear Quartz and it is small in comparison to the body of the Amethyst crystal.
On one side of the crystal point it has a window and the back of the crystal cluster is noted an unusual ridged part of the crystal, we believe it was because that part did not have enough space to grow.
The cluster consists of one big double terminated crystal , with three smaller ones attached to the sides of the main crystal and the base which has smaller clear quartz crystals.
The big point has a chip :(
Skeletal quartz is recognized by its unusual etchings and internal cavities.
Skeletal quartz (more popularly known as Elestial Quartz or Jacare Quartz) exhibits unique internal and external dissolution-growth features resulting from unstable conditions during crystallization.
These skeletal growth features occur most often in the macrocrystalline quartz varieties rock crystal and smoky quartz.
Elestial quartz crystals with natural golden citrine color or natural purple amethyst color are much more rare.
These rare natural golden and purple colors in elestial quartz are due to trace iron impurities in the quartz crystal structure.
Skeletal quartz crystals often form with a geometric pattern of lines, depressions and raised terminations (related to the quartz crystal structure) etched into their surface. Internally, these crystals exhibit plainly visible cavities in geometric patterns (also related to the quartz crystal structure) which can contain clay minerals of varied colors, sometimes accompanied by carbon dioxide or water.
These cavities often have a layered or ribbed aspect and are sometimes so pronounced as to make the crystal almost hollow, giving rise to the term skeletal quartz. Occasionally these cavities contain both liquid and gas phases together known as two-phase inclusions. In rare cases, these two-phase inclusions in quartz can be visible to the unaided eye and may show actual movement of the gas phase within the liquid phase (popularly known as elestial quartz crystal 'enhydros').
Skeletal quartz occurs in vugs or pockets in granitic pegmatites associated with the feldspar varieties microline and albite, and it is occasionally found together with some of the more rare pegmatite minerals such as lepdiolite & amblygonite. Skeletal quartz also occurs occasionally together with some of the rare pegmatite gem varieties such as aquamarine, kunzite, and toumaline.
