Sapphire is a tnoft beautiful Gem of a fine blue 
Colour of all Shades from the deepeft to a pale fky 
blue: it owes its Colour to Copper, and may by 
Fire be made to have a near Refembiance to the 
Diamond : the fineft, which comes to us from the 
East Indies , are equal in Bardnefs to the Ruby ; 
they are now and then found in Europe * but not 
very frequently, or very good. 
Ruby is of a very fine red Colour, with a fmall 
Admixture of purple, which increafes its Beauty : 
its Colour it receives from Gold and Tin. This 
Stone is only found genuine in the Eafi Indies , and 
is always before it is polifhed of a Pebble-like 
Form : when in a perfect State, it is of great Beau¬ 
ty and Value, inferior to none but the Diamond. 
The Diamond is colourlefs, the hardeft and molt 
valuable of all precious Stones: it is brought Tom 
the East Indies, and fome from Brazil , but not fo fine. 
There are in the Table we are now treating of, a 
great Variety of Pearls, particularly one of a purple 
Colour, and another in the Form of a Bunch of 
Grapes; both of which are very rare and valuable 
Specimens.
