The Amethyst (The Stone)
​The most significant Biblical connection here is the purple gemstone. In the Bible, Amethyst (ahlamah in Hebrew) is explicitly named:
​The High Priest’s Breastplate: It was the third stone in the third row of the breastplate of Aaron (Exodus 28:19).
​The New Jerusalem: It is the twelfth foundation stone of the heavenly city (Revelation 21:20).
​Symbolism: In a Biblical context, amethyst often represents royalty, sobriety, and spirituality.
