To determine if a Rudraksha bead is authentic, several tests can be performed. These include examining the surface texture, counting the Mukhis (lines), looking for natural holes, observing its behavior in water, and using a magnifying glass to inspect its structure. More advanced methods, such as X-rays or CT scans, can also be used to confirm the number of compartments within the bead.

Mukhi Count: Authentic Rudraksha beads have clear, natural Mukhis (lines) running from top to bottom, corresponding to the number of compartments within the bead.

Surface Texture: Authentic Rudraksha beads have a rough, uneven, and natural surface texture. Fake beads may be smooth and polished.

Color and Shape: Authentic Rudraksha beads show natural color variations and have a consistent, natural shape.

Water Test: Place the Rudraksha in water. An authentic bead will sink, but a green or air-filled bead may float. A sinking bead is not necessarily authentic, as some fake beads may contain lead.

Copper Coin Test: Place the Rudraksha between two copper coins. If the bead rotates the coins, it could be authentic. However, this test is not conclusive, as any round object can cause rotation.

Thermal Reaction Test: An authentic bead is resistant to breaking or disintegrating after brief exposure to heat.

X-ray or CT scan: These tests can reveal the internal structure of the bead, confirming that the number of compartments matches the Mukhi count.

Lab Certification: Reputable sellers can provide lab certifications for their Rudraksha beads, verifying their authenticity.
