Exodus 28:19

16 Foursquare it shall be [and] double; a span shall be the length thereof, and a span the breadth thereof.

17 And thou shalt set in it settings of stones, four rows of stones: a row of sardius, topaz, and carbuncle shall be the first row;

18 and the second row an emerald, a sapphire, and a diamond;

19 and the third row a jacinth, an agate, and an amethyst;

20 and the fourth row a beryl, and an onyx, and a jasper: they shall be inclosed in gold in their settings.

21 And the stones shall be according to the names of the children of Israel, twelve, according to their names; like the engravings of a signet, every one according to his name, they shall be for the twelve tribes.

22 And thou shalt make upon the breastplate chains like cords, of wreathen work of pure gold.
