Exodus 39:7 (KJV)

And he made the ephod of gold, blue, and purple, and scarlet, and fine twined linen.

And they did beat the gold into thin plates, and cut it into wires, to work it in the blue, and in the purple, and in the scarlet, and in the fine linen, with cunning work.

They made shoulderpieces for it, to couple it together: by the two edges was it coupled together.

And the curious girdle of his ephod, that was upon it, was of the same, according to the work thereof; of gold, blue, and purple, and scarlet, and fine twined linen; as the LORD commanded Moses.

And they wrought onyx stones inclosed in ouches of gold, graven, as signets are graven, with the names of the children of Israel.

And he made the breastplate of cunning work, like the work of the ephod; of gold, blue, and purple, and scarlet, and fine twined linen.

It was foursquare; they made the breastplate double: a span was the length thereof, and a span the breadth thereof, being doubled.

And they set in it four rows of stones: the first row was a sardius, a topaz, and a carbuncle: this was the first row.

And the second row, an emerald, a sapphire, and a diamond.

And the third row, a ligure, an agate, and an amethyst.
