Purity & Identification of Rudraksha

Rudraksha are available from 1 mukhi till 21 mukhis. It is not very difficult to recognize a real Rudraksha. On account of its increasing importance and price, it is made artificially also and these artificial Rudrakshas are also being sold in market. Artificial Rudraksha used to be made long ago by using wild berry seeds or nuts or wood. Life of Rudraksh could be any number of years. If well protected, can be passed on from generation to generation.

There are few methods of testing a genuine Rudraksha:

Water test of Rudraksha : 
. Some times a higher valued Rudraksha (Gaurishanker Rudraksha or a Trijuti ) are made by artificially joining two or three Rudraksha with the help of glue etc. In case of  doubt such Rudraksha should be boiled in water for one to two hours. A sharp discoloration will take place at the joint in case of artificial Rudraksha.
2.If you place a real rudraksha bead in a full glass of water, it would drown in water.

Cut Test of Rudraksha :
A fool proof method is to cut the Rudraksha bead horizontally. One will find the same number of compartments as that of the number of lines . However the drawback is that by this method, the bead gets destroyed.

The Copper coin Test of Rudraksha :
It is generally held that if Rudraksha beads are placed between two copper coins it should rotate slightly. This is due to the physical and magnetic properties of the Rudraksha beads. This test requires a high level of expertise.

Eye Test of Rudraksha :
A fake or the artificial Rudraksha may look like a real one but in these Rudraksha the facets (mukhas) can not be made as real as those present on the real Rudrasha .In a  Rudraksha the facets or the mukhas means deep lining from the upper part to the lower part of Rudraksha .Looking at these deep linings (facets) with the help of a magnifying glass, one can easily recognize a real Rudraksha.

Properties Test of Rudraksha :
The other is to find out whether the beads exhibit properties like inductance, capacitance, conduction of electric current etc. 

Another thing to be noted is that rudraksha being a natural product, it is available in many qualities from low, medium,high to collector. A buyer should avoid low quality beads which are light weight, have broken surfaces and are unshapely and have extremely dry surface. These beads rarely provide any effect. One should go for rudraksha which are heavy, bright, lustrous, shapely and emit a positive vibration.
