Diamonds in the Bible
Two different Hebrew words have been translated by some as “diamond.”
Biblical Hebrew: יַהֲלֹם —transliteration: yahalom —meaning: able to smite, referring to a precious stone
Note that in modern Hebrew the word for diamond is very similar: יהלום.
Three times in Scripture yahalom is used in lists of precious stones. Since this word is derived from the word halam which means to smite, hammer, or strike down, yahalom apparently refers to this precious stones’ hardness.
“and the second row a turquoise, a sapphire and a diamond;” —Exodus 28:18 NASB and Exodus 39:11 NASB
The prophet Ezekiel also mentions a yahalom stone.
Hebrew: שָׁמִיר —transliteration: shamir —meaning: a thorn, briar, a sharp point, a sharp stone
The sin of Judah is written down with an iron stylus;
With a diamond point it is engraved upon the tablet of their heart… —Jeremiah 17:1 NASB excerpt
From its hardness, it was used for cutting and perforating other minerals. It is the hardest and most valuable of precious stones. It is translated as “adamant” in the King James Version of Ezekiel 3:9 and Zechariah 7:12.
The foundation stones of the city wall were adorned with every kind of precious stone. The first foundation stone was jasper; the second, sapphire; the third, chalcedony; the fourth, emerald; the fifth, sardonyx; the sixth, sardius; the seventh, chrysolite; the eighth, beryl; the ninth, topaz; the tenth, chrysoprase; the eleventh, jacinth; the twelfth, amethyst. And the twelve gates were twelve pearls; each one of the gates was a single pearl. And the street of the city was pure gold, like transparent glass. —Revelation 21:19-21 LSB
