Rudraksha (IAST:Rudrākṣa, Devanagari: रुद्राक्ष, Bengali: রুদ্রাক্ষ, Kannada:ರುದ್ರಾಕ್ಷಿ, Telugu: రుద్రాక్ష, Tamil:ருத்ராட்ச) is a seed traditionally used as prayer beads in Hinduism (especially Shaivism). Rudraksha bead are covered by an outer shell of blue color on fully ripening, hence also called blueberry beads. The seed is produced by several species of large evergreen broad-leaved tree in the genus Elaeocarpus, with Elaeocarpus ganitrus roxb being the principal specie. They are associated with the Hindu deity Lord Shiva and are commonly worn for protection and chanting Om Namah Shivaya mantra by devotees. The seeds are primarily used in India and Nepal as beads for organic jewellery and malas and are valued similarly to semi-precious stones. Various meanings and potencies are attributed to beads with different numbers of segments (faces/mukh) and rare or unique beads are highly prized and valuable.
Rudraksha is a Sanskrit compound word consisting of the Rudra (Sanskrit: रुद्र) and akṣa (Sanskrit: अक्ष ). Rudra is one of Lord Shiva's vedic names and Akṣa means 'teardrops'. So it means Lord Rudra's (Lord Shiva's) teardrops.
There are other sources like Satguru Sivaya Subramuniyaswami and Kamal Narayan Seetha who describes Akṣa as eye. So meaning of Rudraksha could also constitutes as "Eye of Lord Shiva" or "Eye of Rudra". 
Significance and Spiritual Use
Rudraksha term is used both for the berries themselves and as a term for the type of mala made from them. There is a long tradition of wearing Rudraksha beads in India, particularly among Shaivism, due to their association with Lord Shiva. Lord Shiva himself wears rudraksha garlands. Om Namah Shivaya mantra is repeated (japa) using the rudraksha beads. Rudraksha malas have been used by Hindus as rosaries from at least the 10th century  for meditation purposes and to sanctify the mind, body and soul.
Rudraksha beads may be strung together as a mala and used to count the repetition of a mantra or prayer, similar to the use of rosaries in Christianity. Most garlands contain 108 beads plus one, as 108 is considered sacred and a suitable number of times to recite a short mantra. The extra bead, called the "Meru", bindu or "guru bead", helps mark the beginning and end of a cycle of 108, as well as having symbolic value as a 'principle' bead. While counting the mala the meru should not be overtaken but when meru is reached then mala is recited in reverse order. Recitation should be done after covering the mala and it should not touch the ground. After recitation mala should be kept in cotton bag. Rudraksha mala's usually contain beads in following combination: 27+1, 54+1 or 108+1. 54+1 needs to be recited twice for one complete round. 27+1 needs to be recited four time for one complete round. It is possible to carry a single seed or several seeds strung on the same thread. Devi-Bhagavata Purana describes preparation of rudraksha mala. Rudraksha till 14 mukhi found reference in Shiva Purana, Padma Purana, Devi-Bhagavata Purana, Skanda Purana etc. The beads are commonly strung in silk or in a black or red cotton thread. Less often, jewellers may use copper, silver or gold wires though the rudraksha may be damaged if strung too tightly.
Description of the tree
Elaeocarpus ganitrus roxb grows 60-80 feet and are found from the Gangetic plain in the foothills of the Himalayas to Southeast Asia, India, Nepal, Indonesia, New Guinea to Australia, Guam,Hawaii, China, Taiwan, parts of Malaysia and Java(Indonesia). Out of 300 species of Elaeocarpus 35 are found in India.
Rudraksha seeds are covered by an outer husk of blue when fully ripe, and for this reason are also known as blueberry beads. The blue color is not derived from pigment but is structural. It is an evergreen tree that grows quickly. The Rudraksha tree starts bearing fruit in three to four years from germination. As the tree matures, the roots form buttresses, rising up near the trunk and radiating out along the surface of the ground.
General information on the Rudraksha tree: found from sea level up to 3000m above. The Rudraksha tree grows in a narrow space, not on open ground. Its leaves resemble those of tamarind or nux vomica, but are longer. It yields one to two thousand fruits annually. These fruits are also known as Amritphala (Fruits of Nectar).
Type of Rudraksha beads
Rudraksha bead are found in from 1 to 21 mukhi. Recently 27 mukhi rudraksha was found in Nepal. 80% of all rudraksha are 4, 5 (most common) and 6 mukhi. 1 mukhi is rearest bead. Rudraksha from Nepal are of bigger size (25-30 mm) and Indonesian rudraksha are smaller in size(4-12 mm). Rudraksha are available in white, red, brown (most common), yellow and black color.
There are special type of rudraksha available like Gauri Shankar (two Rudraksha are naturally joined), Ganesha (a Rudraksha having trunk like protrusion on its body), Sawar (a Gauri Shankar in which one bead has only one line or Mukh), Trijuti (three Rudraksha-beads joined naturally) and the rare ones like Ved (4 Sawars on a bead) ,Dwaita (Two sawars on the bead etc).
Surface texture of Rudraksha bead
A Rudraksha's surface should be hard and the projections should be well grooved, as found in most of the Nepalese Rudrakshas. Indonesian Rudraksha has a different appearance. Rudraksha from India shows very high and deeply grooved projections resembling natural deep hills and valleys.
Most faked rudraksha are 1 mukhi due to it's rarity. A variety of rudraksha called 1 mukhi half-moon is thus sold in its place which is genuine and more easily available version of 1 mukhi rudraksha. 1 mukhi is faked using berries and Areca nut. Also some suppliers sell fake rudraksha which have Serpent, Trishul, Shiva-lingam etc carved on them. A real rudraksha does not have these markings. Fake rudraksha are also made by carving extra lines on lower mukhi rudraksha to obtain the rare and higher priced higher-mukhi rudraksha or by hiding lines to make a rarer lower mukhi rudraksha. Also fake Gauri Shankar rudraksha is made by gluing together two rudraksha beads.
To recognize real rudraksha many technique are used like sinking and floating of rudraksha as well as revolving rudraksha in between two copper coins. But these are not correct criteria. Some techniques which helps:-
- Use magnifying glass and examine for artificially carved lines which are generally very sharp and glued surfaces on the bead.
- Whenever checking genuinity of a joint or of a line on rudraksha for example checking a Gauri shankar for joints or lines in higher mukhi then make sure to boil rudraksha in water for 1 to 2 hours. Sharp discoloration will take place at the joint or at the artificially created line.
- Cut the bead horizontally. There are same number of compartments as that of the number of lines on rudraksha.
- Best of all is doing x-ray of the rudraksha.
Rudraksha beads contain carbon, nitrogen, hydrogen, oxygen and trace elements in combined form. The Rudraksha fruit have many phytoconstituents such as alkaloids, Flavonoid, Tannin, steroids, Triterpene, carbohydrates and cardiac Glycoside. It contain Rudrakine, a new found alkaloid

- अथ कालाग्निरुद्रं भगवन्तं सनत्कुमारः पप्रच्छाधीहि भगवन्रुद्राक्षधारणविधिं स होवाच रुद्रस्य नयनादुत्पन्ना रुद्राक्षा इति लोके ख्यायन्ते सदाशिवः संहारकाले संहारं कृत्वा संहाराक्षं मुकुलीकरोति तन्नयनाज्जाता रुद्राक्षा इति होवाच तस्माद्रुद्राक्षत्वमिति तद्रुद्राक्षे वाग्विषये कृते दशगोप्रदानेन यत्फलमवाप्नोति तत्फलमश्नुते स एष भस्मज्योती रुद्राक्ष इति तद्रुद्राक्षं करेण स्पृष्ट्वा धारणमात्रेण द्विसहस्रगोप्रदानफलं भवति । तद्रुद्राक्षे एकादशरुद्रत्वं च गच्छति । तद्रुद्राक्षे शिरसि धार्यमाणे कोटिगोप्रदानफलं भवति । Brihajjabala Upanishad
Meaning: Sage Sanatkumara approached Lord Kalagni Rudra and asked him, "Lord, kindly explain me the method of wearing Rudraksha." What he told him was, "Rudraksha became famous by that name because initially, it was produced from the eyes of Rudra. During the time of destruction and after the act of destruction, when Rudra closed his eye of destruction, Rudraksha was produced from that eye. That is the Rudraksha property of Rudraksha. Just by touching and wearing this Rudraksha, one gets the same effect of giving in charity one thousand cows."

- हृदयं कुण्डली भस्मरुद्राक्षगणदर्शनम् । तारसारं महावाक्यं पञ्चब्रह्माग्निहोत्रकम् ॥ Rudrahridaya Upanishad
Meaning: After prostrating before the celebrated form of Sri Mahadeva-Rudra in his heart, adoring the sacred Bhasma and Rudraksha and mentally reciting the great Mahavakya-Mantra, Tarasara, Sage Shuka asked his father Geat Sage Vyasa 
- अथ हैनं कालाग्निरुद्रं भुसुण्डः पप्रच्छ कथं रुद्राक्षोत्पत्तिः । तद्धारणात्किं फलमिति । तं होवाच भगवान्कालाग्निरुद्रः । त्रिपुरवधार्थमहं निमीलिताक्षोऽभवम् ।निमीलिताक्षोऽभवम् तेभ्यो जलबिन्दवो भूमौ पतितास्ते रुद्राक्षा जाताः । सर्वानुग्रहार्थाय तेषां नामोच्चारणमात्रेण दशगोप्रदानफलं दर्शनस्पर्शनाभ्यां द्विगुणं फलमत ऊर्ध्वं वक्तुं न शक्नोमि । Rudrakshajabala Upanishad
Meaning: Sage Bhusunda questioned Lord Kalagni-Rudra: What is the beginning of Rudraksha beads? What is the benefit of wearing them on the body? Lord Kalagni-Rudra answered him thus: I closed my eyes for the sake of destroying the Tripurasura. From my eyes thus closed, drops of water fell on the earth. These drops of tears turned into Rudrakshas. By the mere utterance of the name of 'Rudraksha', one acquires the benefit of giving ten cows in charity. By seeing and touching it, one attains double that benefit. I am unable to praise it any more.
- They who walk the twin paths of charya and kriya ever praise the twin feet of the Lord. They wear holy emblems—the twin rings in earlobes, the twin rudraksha garland around the neck—and adopt the twin mudras, all in amiable constancy. : Tirumantiram 1423. TM
- Thinking of Him, great love welling up in their heart, if they finger the rudraksha beads, it will bring them the glory of the Gods. Chant our naked Lord’s name. Say, “Namah Shivaya!” : Tirumurai 3.307.3. PS, 217
