Inclusions are a natural consequence of crystal growth and even the best stones are not expected to be totally inclusion-free.

Opaque, included and lifeless sapphires are in a lower grade and have low value in the gemstone industry, and not used in fine jewelry.
We must remember that the most powerful of all is our mind power. The use of gemstones in the chemical, wave and vibration energy of the gemstones can only be of some help to the well being of man. It is like a fence on the stairs. The stair fence is not essential for climbing stairs. But having a stair fence will make it easier to climb the stairs. That is also the case with using a gemstone. Almost every gem has its own vibrational and waves energy. also, the chemical properties of the gemstones are very special. Gemstones are used to cure diseases and to stimulate and balance the energy fields of the human body by the chemical composition and other energies of the gemstones.
