Exodus 39:9-13

It was square; they made the breastpiece folded double, a span long and a span wide when folded double.

And they mounted four rows of stones on it. The first row was a row of ruby, topaz, and emerald;

and the second row, a turquoise, a sapphire, and a diamond;

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

and the fourth row, a beryl, an onyx, and a jasper. They were set in gold filigree settings when they were mounted.
