Chrysolithos means 'gold stone,' a golden-yellow precious stone, possibly what we call topaz today (though ancient gemstone identifications are sometimes uncertain). John lists it as the seventh foundation stone in his vision of the New Jerusalem's foundations. Each of the twelve foundation stones contributes a different color and luster to the city's beauty, together displaying the radiant glory of God's eternal dwelling. The golden hue of chrysolite adds warmth to the spectrum of jewels adorning the city's foundations, all reflecting the light of God's glory.
