Tests of Lapis Lazuli (Vaidurya) ||73||

1Suta said: -O thou twice-born one, the mode of testing such gems as the Vaiduryya, the Padmaraga, the Karketana and the Bishma stone, were first described by the god Brahma to the holy sage Vyasa, who subsequently disclosed them to the world for the good of the human race.
2The bosom of that primordial ocean was violently agitated by the thundering war-cry of that lord of the demons, whose swollen and frenzied waters began of madly lash the jagged faces of its rock-bound coasts; and behold, Vaiduryyas of varied colours and matchless brilliance; were showered down through the clefts of those water-river shores, turning them into beds of shining light.
3Accordingly the brown of the contiguous hill of Vidura was tans formed into a mine of Vaidutyya, which was originated by the war cry of the demon Vala and is named after the rock in which it was first found to be imbedded.
4-5The thunder like roar of the demon, gave rise to the formation of packs of sable clouds, and Vaiduryyas of varied colours were formed under their influence, as so many effulgent shootings off form that primordial sky.
6-7Colours which mark the several classes of the Padmaraga, as well form the distinctive features of the several species of the Vaiduryya, of which those that are tinged like the breast feathers of a peacock, or coloured pale green like the leaves of a bamboo, are the best as regards price and quality. A Vaiquryya, possessed of a blended hue like that of the primary or the exterior feathers of the wings of a Casha (bird) occupies the lower place in the list as regards value and intrinsic virtues, and accordingly its use if forbidden by the gem experts.
8A Vaicjuryya, belonging to the commendable type, brings good luck to its wearer, whereas the use of one of the condemnable species, is attended with dreadful consequences. Hence a Vaiduryya should be carefully observed and tested before wearing.
9Stones, known as the Girikaca, Sisupala, or glass crystals, appearing as clouded smoke, may be easily mistaken for a Vaiduryya, though – they are alien to it in species.
10They should be pronounced as bits of glass in the event of their proving incapable of cutting or scratching a Vaiduryya of tested genuineness, whereas a Saisopalakam stone, simulating the properties of a Vaiduryya, should be detected by its lightness. A crystal, mistaken for a gem of the species under discussion, should detected by its greater brilliance.
11The price of two pala weights of Vaiduryya, should be laid at the amount fixed for the value of a Suvama weight of Indra-Nnam.
12-14aGems apparently resembling a Vaiduryya in colour, but virtually belonging to the alien species, should be compared in respect of gloss, softness, lighter weight, etc., with a Vaiduryya of tested genuineness. The price of a Vaiduryya, in common with the rest of the gems, varies according to its setting and purification and depends upon the fact of its being possessed of auspicious or inauspicious features.
14b-15Found in a mine of Samateta or in a country near the seacoast, should be valued at a price six times greater than that of an ordinary gem belonging to the same species.
16The price enumerated above, should be deemed as obtaining in markets near the seacoast and in vicinity of the gem mines.
17-19Sixteen Msakas are equivalent to a weight, technically known as the Suvani.am in the parlance of the gem dealers, a seventh part whereof is called a Sana. Four Krsnalas make a Masa or a Msaka. A tenth part of a Pala makes a Dharana.
