“….upon the throne one sitting. And he that sat, was to the sight like the jasper and the sardine stone.”
Sard! Sard! Is that so hard?
“….on the Throne was seated One Whose appearance had a gemlike sparkle as of jasper and carnelian.”
I’m pretty sure I never thought of the Lord as sparkly.
“The one sitting there looked like gray quartz and red quartz.”
That would be the no-geology-in-the-soul translation.
