Barnes' Notes
The gold of Ophir - Uniformly spoken of as the most precious gold; see the notes at Job 22:24.
With the precious onyx - The onyx is a semi-pellucid gem, with variously colored veins or zones. It is a variety of the chalcedony. The Arabic word denotes that which was of two colors, where the white predominated. The Greeks gave the name "onyx" ̓́ onux to the gem from its resemblance to the color of the thumbnail; see Passow.
Or the sapphire - See the notes at Job 28:6.
