The Greek translation of the Old Testament does not refer to a “tested stone” but to a “choice” or “chosen stone.” Peter quotes the passage using the same term, “choice stone.” The Hebrew word bokhan can mean refined; in that sense, something can be chosen because it has been tested and proved. Other writers think that bokhan means “strong.”
The word stone sometimes stands in its various forms as a prophetic messianic name of Jesus (Yeshua‘). He is also the cornerstone. One of the names for God is Stone of Israel.
Tested Stone in Hebrew:

Bible reference: Isa. 28:16
See, I lay a stone in Zion, a tested stone,
a precious cornerstone for a sure foundation;
the one who relies on it
will never be stricken with panic. (Isaiah 28:16 NIV)
