CHAP. XII. The Authors Journey to the other Mines; and how they find the Diamonds there.
SEven days journey from Golconda Eastward there is another Diamond Mine, call'd in the language of the Country Gani, in the Persian tongue Coulour. It is near a great Town, by which the same River runs, which I cross'd coming from the other Mine; and a League and a half from the Town is a high Moun∣tain in the form of a Half-Moon; the space between the Town and the Moun∣tain is a Plain where they dig and find Diamonds. The nearer they dig to the Mountain, the larger Stones they find; but at the top they find nothing at all.
It is not above a hundred years since this Mine was found out by a Country∣man, who digging in a piece of ground to sow Millet, found therein a pointed Stone that weigh'd above twenty-five Carats; he not knowing what the Stone was, but seeing it glister, carry'd it to Golconda, where as it happen'd well for him, he met with one that traded in Diamonds. The Merchant in∣forming himself of the place where the Stone was found, admir'd to see a Jewel of that bigness, not having seen any one before that weigh'd above ten or twelve Carats. However his report made a great noise in the Country; insomuch that the Mony'd men in the Town set themselves to work, and causing the ground to be search'd, they found, and still do find bigger Stones, and in greater quan∣tity than in any other Mine. For they found a great number of Stones from ten to forty Carats, and sometimes bigger; among the rest that large Stone that weigh'd nine hundred Carats, which Mirgimola presented to Aureng-zeb.
But though this Mine of Coulour be so considerable for the quantity of great Stones which are there found, yet the mischief is, the Stones are not clean; the Waters having something of the quality of the Earth where they are found. If the Ground be mershy, the Water enclines to black; if it be red, there is a redness in the Water; in other places the Stones appear somewhat greenish, in others yellowish; such a diversity of Soils there is between the Town and the Mountain. Upon the most part of these Stones after they are cut, there appears a kind of greasie moisture, which must be as often wip'd off.
As for the Water of the Stones, it is remarkable, that whereas in Europe we make use of day-light to examine the rough Stones, and to judg of their Water, and the specks that are found therein, the Indians do all that in the night-time, setting up a Lamp with a large Wiek, in a hole which they make in the Wall, about a soot square; by the light whereof they judg of the Wa∣ter and clearness of the Stone, which they hold between their Fingers. The Water which they call celestial is the worst of all, and it is impossible to discern it so long as the Stone is rough. The most infallible way to find out that Wa∣ter,
