'Sardius' in the Bible

thou wast in Eden, the garden of God. Every precious stone was thy covering: the sardius, the topaz, and the diamond, the chrysolite, the onyx, and the jasper, the sapphire, the carbuncle, and the emerald, and gold. The workmanship of thy tambours and of thy pipes was in thee: in the day that thou wast created were they prepared.

and he that was sitting like in appearance to a stone of jasper and a sardius, and a rainbow round the throne like in appearance to an emerald.

the fifth, sardonyx; the sixth, sardius; the seventh, chrysolite; the eighth, beryl; the ninth, topaz; the tenth, chrysoprasus; the eleventh, jacinth; the twelfth, amethyst.
