Fill a basin, made of silver, with a water of Ganges and keep it in Ishaan. Now, light a Deepak of pure ghee in Aagneye. Burn Agarbatti/Dhoop in the Vayavya. Place a china clay bowl filled with clear Yamuna sand in Nainrritya direction.
Sit in between all these elements i.e. space element, facing North direction. Now concentrate your mind on the energies of the Gem and take it in your hand. Now place the gem in the sand and touch it 7 times, saying:
I purify you(gem) with water!
Now, clean the dust and hold it in the Dhoop, passing here 7 times through the smoke, saying:
I purify you with air!
