_Amethysts_ are found in the gneiss, and some discoloured though beautiful specimens in syenite; they are too common to be highly esteemed. The "Matura Diamonds," which are largely used by the native jewellers, consist of zircon, found in the syenite not only uncoloured, but also of pink and yellow tints, the former passing for rubies.
But one of the prettiest though commonest gems in the island is the "Moon-stone," a variety of pearly adularia presenting chatoyant rays when simply polished. They are so abundant that the finest specimens may be bought for a few shillings. These, with _aqua marina_, a bad description of _opal rock crystal_ in extremely large pieces, _tourmaline_, and a number of others of no great value, compose the list of native gems procurable in Ceylon.[1] Diamonds, emeralds, agates, carnelians, opal and turquoise, when they are exhibited by the natives, have all been imported from India.
[Footnote 1: Caswini and some of the Arabian geographers assert that the diamond is found at Adam's Peak; but this is improbable, as there is no formation resembling the _cascalhao_ of Brazil or the diamond conglomerate of Golconda. If diamonds were offered for sale in Ceylon, in the time of the Arab navigators, they must have been brought thither from India, (_Journ. As. Soc. Beng._ xiii. 633.)]
During the dynasty of the Kandyan sovereigns, the right of digging for gems was a royalty reserved jealously for the King; and the inhabitants of particular villages were employed in their search under the superintendence of hereditary officers, with the rank of "Mudianse." By the British Government the monopoly was early abolished as a source of revenue, and no license is now required by the jewel-hunters.
Great numbers of persons of the worst-regulated habits are constantly engaged in this exciting and precarious trade; and serious demoralisation is engendered amongst the villagers by the idle and dissolute adventurers who resort to Saffragam. Systematic industry suffers, and the cultivation of the land is frequently neglected whilst its owners are absorbed in these speculative and tantalising occupations.
The products of their searches are disposed of to the Moors, who resort to Saffragam from the low country, carrying up cloth and salt, to be exchanged for gems and coffee. At the annual Buddhist festival of the Pera-hara, a jewel-fair is held at Ratnapoora, to which the purchasers resort from all parts of Ceylon. Of late years, however, the condition of the people in Saffragam has so much improved that it has become difficult to obtain the finest jewels, the wealthier natives preferring to retain them as investments: they part with them reluctantly, and only for gold, which they find equally convenient for concealment.[1]
