I was given 2 of these wonderful beads by a friend who just returned from a trip to Hawaii.
Iraivan Hindu Temple put out and information sheet and they write, "Two decades ago on the Garden Idland of Kauai, the Hindu monks planted a forest of 250 Rudraksha trees. Today it is America's only grove of tree called Blue Marble by the Hawaiians and Eleocarpus ganitrus in Latin. The magnetic power inherent in these beads is immensely effective to our body and mind and hence wearing a rudraksha brings good health and mental peace."
