'Luster' in the Bible

(Alef)Alas! Gold has lost its luster; pure gold loses value. Jewels are scattered on every street corner.

I looked, and there were four wheels beside the cherubim, one wheel beside each cherub. The luster of the wheels was like the gleam of beryl.

His body also was like beryl [with a golden luster], his face had the appearance of lightning, his eyes were like flaming torches, his arms and his feet like the gleam of burnished bronze, and the sound of his words was like the noise of a multitude [of people or the roaring of the sea].

having God’s glory [filled with His radiant light]. The brilliance of it resembled a rare and very precious jewel, like jasper, shining and clear as crystal.
