 can possess but themselves. In their eyes the merit of an object which is in any degree either useful or beautiful, is greatly enhanced by its scarcity, or by the great labor which it requires to collect any considerable quantity of it, a labor which nobody can afford to pay but themselves. Such objects they are willing to purchase at a higher price than things much more beautiful and useful, but more common. These qualities of utility, beauty, and scarcity are the original foundation of the high price of those metals, or of the great quantity of other goods for which they can everywhere be exchanged. This value was antecedent to and independent of their being employed as coin, and was the quality which fitted them for that employment. That employment, however, by occasioning a new demand, and by diminishing the quantity which could be employed in any other way, may have afterward contributed to keep up or increase their value.

The demand for the precious stones arises altogether from their beauty. They are of no use, but as ornaments; and the merit of their beauty is greatly enhanced by their scarcity, or by the difficulty and expense of getting them from the mine. Wages and profit accordingly make up, upon most occasions, almost the whole of their high price. Rent comes in but for a very small share; frequently for no share; and the most fertile mines only afford any considerable rent. When Tavernier, a jeweller, visited the diamond mines of Golconda and Visiapour, he was informed that the sovereign of the country, for whose benefit they were wrought, had ordered all of them to be shut up, except those which yield the largest and finest stones. The others, it seems, were to the proprietor not worth the working.
