In ceremonial worship the Hindus recognize sixteen offerings, the ninth consisting of gems and jewelry, and a divine assurance of adequate return to the giver appears in the Bhagavat Purana, where Krishna says, “Whatever is best and most valued in this world and that which is most dear to you should be offered to me, and it will be received back in immense and endless quantity.” On certain appointed days the holy images are decorated with the choicest garments and the richest jewelry in the temple treasury; this is especially the case on the day celebrated as the birthday of the respective divinity. However, the gifts are believed to retain their sacred character as dedicated objects only for a comparatively brief period, varying from a month or more for garments and vestments, to ten or twelve years for jewels, such as the naoratna or the panchratna, the prized and revered jewels, composed respectively of nine and five gems. The panchratna usually consists of gold, diamond, sapphire, ruby, and pearl. After the gifts have ceased to be worthy of use in the temples, they may be disposed of to defray the expenses of the foundation, including the cost of supporting the numerous priests and attendants. As the objects still retain their sacred associations, they are eagerly bought by pious Hindus, who undoubtedly regard them as valuable talismans. Thus they not only serve to bring blessings upon the donors, but also constitute one of the chief sources of income for the temples.[364] One of the oldest and perhaps the most interesting talismanic jewel is that known as the naoratna or nararatna, the “nine-gem” jewel. It is mentioned in the old Hindu ratnaçastras, or treatises on gems, for example, in the Nararatnaparîkshâ, where it is described as follows:[365] Manner of composing the setting of a ring: In the centre The Sun The Ruby To the East Venus The Diamond To the Southeast The Moon The Pearl To the South Mars The Coral To the Southwest Râhu The Jacinth To the West Saturn The Sapphire To the Northeast Jupiter The Topaz To the North The descending node The Cat’s-eye To the Northwest Mercury The Emerald Such is the planetary setting. From this description we learn that the jewel was designed to combine all the powerful astrological influences. The gems chosen to correspond with the various heavenly bodies, and with the aspects known as the ascending and descending nodes, differ in some cases from those selected in the West. For instance, the emerald is here assigned to Mercury, whereas in Western tradition this stone was usually the representative of Venus, although it is sometimes associated with Mercury also.[366] On the other hand, the diamond is dedicated to Venus, instead of to the Sun as in the Western world.
