The shell of the pearl-oysters is not used locally, but large quantities are exported to Europe for manufacture. Although it is the smallest and cheapest produced in the gulf, yet, owing to the enormous quantity taken for their pearls, the shell of the mahar (Margaritifera vulgaris) constitutes the bulk of the exports. Formerly most of the shipments were made from the harbor of Lingah, hence it is known in the markets of Europe as “Lingah shell.” But in the last three or four years, much of it has been transported to Europe via Bander Abbas and Bushire. A German firm at Bahrein is extensively employed in exporting this shell, and several Indian merchants are also engaged in the trade. The total exports in 1906 amounted to 3262 tons, valued at $26,408 according to the port returns, but worth about $135,000 in Europe. Very large quantities are received in London, and over 2500 tons have been offered at auction in a single year. This shell is very small, averaging about three inches in diameter and about one and a half ounces in weight. It is the cheapest of all mother-of-pearl. The best quality sells in London for ten to twenty shillings per hundredweight, but the ordinary grade is worth usually less than nine shillings, and sometimes as low as three shillings per hundredweight. America formerly imported it, but few lots have been received since the exploitation of the Mississippi shell about fifteen years ago.
