rent than the Peruvian, which has generally clouds found in it,
and fparkles lefs.

And, befides, there are fuch quantities brought from Peru by
the way of Carthagena, that' the value and reputation of them
is much funk.

The Emerald is fuppofed to grow more and more perfect in
the mine like the ruby, and to arrive at its greennefs by flow de-
grees.

It is a common opinion that the Emerald grows in the jafper,
and it is certain there are fome jafpers fo perfectly green, that
they have, by many, been taken for Emeralds.

The proper matrix or marcafite of this ftone is the premc,
which is reckoned among the coarfer precious ftones; beinghard,
tranfparent, half opapue, and ufually intermixed with yellow,
white, green, blue, &c.

Some authors make mention of feveral Emeralds of incredible
magnitude ; as a table which king Tarik had for his fhare of the
plunder of Toledo, a table three hundred fixty-five feet long,
and all of a piece, which was an Emerald. And Theophraflus
relates, that he had feen in a temple in Egypt one of four cubits
long, and three broad \ andj alfo, fome mention an obelifk of
Emerald forty feet high.

Some authors are of opinion, that Emeralds are taken out of
Iron mines. And Pomet afferts, that he had one to which the
iron ore was ftiil flicking.

Some tell us of Emeralds found in Cyprus, and even in Great
Britain ; but, if there are of them any true ones at all, they are
not considerable.

In M. Savary's Dictionary de Commerce, there is the follow-
ing accurate eftimate of the values of the different kinds of Peru-
vian Emeralds, as follows :

Rough Emeralds. Thofe of the firft and coarfeft fort, called
plafmes for grinding, are worth twenty-feven millings fterling'
the mark, or eight ounces.

The demi-morillons, eight pounds fierling per mark.

Good morillons, which are only little pieces, but of fine co-
lour, from thirteen to fifteen pounds per mark.

Emeralds larger than morillons, and called of the third colour
or fort, are valued at, from fifty to lixty pounds per mark.

Emeralds, called of the fecond fort, which are in larger and
finer pieces than the preceding, are worth from fixty-five to fe-
venty-five pounds per mark.

Laftly, thofe of the firft colour, otherwife called negres cartes,
are worth from a hundred and ten to a hundred and fifteen pounds
per mark.
