INCLUSIONS AND CRACKS IN NATURAL STONES
By purchasing a natural stone, you get not just an ornament, but a certain energy that it carries with it. Ideally pure stones, like glass, cannot tell you anything about their history. While minerals with natural inclusions and cracks contain a multi-thousand-year history of their formation, their character and “soul”. In addition, the presence of inclusions in the stone is a clear sign of its natural origin.
Slice of belomorite with iridescence
As solid inclusions in stones, there are either minerals of the same type (for example, garnet in garnet), or alien minerals (for example, rutile in quartz). They can appear earlier than the stone itself, and be captured by it in the process of its formation, or crystallize from the melt simultaneously with it, and finally, they may appear as a result of subsequent processes of decomposition of the solid solution occurring inside the stone itself.
Amethyst and quartz crystals on rock
Along with minerals, solid inclusions also include signs of growth. These include polycrystalline twin formations (for example, polysynthetic twinning in a moonstone) and zonal structure. The appearance of the latter causes a stop in the growth of the crystal; it is especially beautifully expressed in crystals of tourmaline, corundum, garnet, beryl and some other minerals.
Quartz with chlorite inclusions
Liquid inclusions in gemstones occur in the form of large liquid-filled cavities and "tails" or "clouds" (turbid bands with blurry contours, overflowing with liquid micro-inclusions). Often such inclusions are residual solutions that have arisen during the crystallization of the initial melt, or they consist of water or liquid carbon dioxide; partly their nature has not yet been elucidated. The voids in which they are enclosed are formed during the growth of crystals, when, for some reason, free volumes appear in the structure of the latter.
Tourmaline and Clevelandite
There are a number of semi-precious stones, which, due to their special structure, have internal “cracks” that are not cracks, but are signs of uneven growth of the mineral or features of the crystal structure. This is especially pronounced in such stones as labradorite, moonstone (adularia, belomorite), kyanite, some varieties of quartz and garnets.

If you want your talisman to be a “living” stone, then you should not be afraid of minerals with natural inclusions, as they are not just beautiful glass, they carry with them a special energy that you may need.
