Sardine (Stone)

Wilson's Dictionary of Bible Types

Ezekiel 28:13 (b) Probably the Lord is telling us that all the beauty of Heaven's adornments as represented by the different colors of stones was given to this great arch-angel who later fell and became Satan. These stones represent a wide variety in values, so that probably we are being told that Satan in his original exalted position with GOD had all the values that could be given to a created spirit.
