How Rudraksha Identified in Lab?

Methods for Identification of Rudraksha-
Eye test
Sometimes the fake or the Artificial Rudraksha may seen same as real one but these fake Rudraksha facets cannot be made as real as those present on the real Rudraksha. This is a Natural partition on Elaeocarpus which just like the closed lips with deep natural. Under Microscope/Magnifying Glass (Lenses) this can be easily distinguish between fake or real Rudraksha
Water test
Some of the rare Rudraksha beads like Gauri Shankar or a Trijuti Rudraksha, It can be made by synthetically joining two or three Rudraksha with help of paste/Glue/Resin etc. if here is any of hesitation then Kept the seed in to hot boiling water for some minutes. A sharp streak will take place at the joint of seed.
X-Ray
One way is to follow the X-ray technique one can see the internal structure without damaging the beads. This digital X-ray test is done without complication for Rudraksha up to nine Mukhi but higher Mukhi beads may not give 100% accurate results due to overlapping of the internal compartment of seeds.
Magnetic Resonance Imaging
MRI is another method for identification of Rudraksha but it is more expensive than X-ray. It gives much clear results for any Rudraksha than X-ray.
Cut Test
It is most reliable methods and for this we have to cut the beads horizontally. When it will be cut one can find the same number of section as the number of lines. Drawback of this method is that bead gets damaged.
1 Mukhi Nepali Rudraksh exist?

If someone has sold you a Rudraksha saying it is Ek-Mukhi Nepal, you must realize the bead is fake. Ek mukhi Nepal Rudraksha is extremely rare and hasn't been known to reach the general public. Today it exists only in mythology. Nobody haven't seen an Ek-mukhi Rudraksha being produced from the trees.
Because of the high virtues of this Rudraksha in Vedic texts, the market is full of fake Ek-Mukhis which are made by cutting segments out of 2,3,4 or 5 faced Rudraksha and removing all lines expect one. A 2-mukhi Rudraksha from Haridwar and Nepal is also used to make 1 mukhi because here, only one line needs to be removed. In some 2 Mukhi and 3 Mukhi beads, the lines are not fully developed and you can see the incomplete lines at the mouth. Sometimes, a 2 Mukhi Nepal bead is fastened with a steel grip on the tree itself so that the second line isn’t formed and this bead is sold as 1-mukhi.
How we can know whether a Rudraksha is Natural or Duplicates?

You Must take a Report from a Reputed Rudraksha Testing Laboratory like OIGS.
