'Sparkling' in the Bible

Their legs were straight, and the soles of their feet were like the hooves of a calf, sparkling like the gleam of polished bronze.

The appearance of the wheels and their workmanship was like sparkling beryl, and all four of them had the same form, their appearance and workmanship being as if one wheel were within another.

Then I looked and behold, [there were] four wheels beside the cherubim, one wheel beside one cherub and another wheel beside each other cherub; and the appearance of the wheels was like a sparkling Tarshish stone (beryl).
