The pearl fisheries of Oman and the countries that follow it; Abyssinia and Yemen. The begin is the Gulf
of Oman, then comes Muscat, Al Sihr, Socotra, the Gulf Aden and Berbera: the sea is 10 qaymans deep;
from there come all the big pearls who are the most white, and most expensive; small ones are rare; they
are better then the Qatari, because of their size they have not the roundness of the Qatari, but their
transparency is bigger, their whiteness more intense and they are close one to the other. There is in the
pearl fishery of Oman a special oyster called harkus: it is a long oyster and if there is in one a grain, it is
big and pure; the pearl fisheries of the gulf of Zendj are also part of Oman; one fishes only small quantities
and finds hardly anything; if a pearl is found, it is big as a umani or a bid less: there are no balbal.
