“Om Sathguru Sri Seshadri Swamigal Thiruvadikkae”
Please remember that crystals and gemstones absorb, hold, and emit vibrations.
Any crystal in its natural state (in the earth), is pure and strong.
When you buy a piece of crystal or gemstone jewellery, either online, or in person, from the moment, it is mined, cleaned, cut, drilled and polished, it would have passed through a hundred pair of hands before it finally reaches you! In all of this, it would have picked up the energies of all those who had been handling it! By this time, it would have become vibrationally weak.
Using it as it is, would not yield any healing. Hence the need to cleanse it. There are various ways of cleansing crystals. All gemstones cannot be cleansed in all ways.
To benefit its potential strength, it is very much necessary to cleanse your gemstone jewellery before you wear it.
Therefore, in the case of gemstone jewellery, it is enough to clean the necklace/bracelet/earrings/pendant by under a tap of running water for a minute or so.
This would clear all the previous energies it has held, and becomes once again, clean and pure to wear. To amplify its energy, one can energize it through Reiki.
