I am not sure of the materials used in this set of candle holders.  Wikipedia says that Niello is a black mixture of copper, silver, and lead used as an inlay on engraved or etched metal.  The main part of the candle holders looks like brass.  The center ball could be silver or some other metal, but it is evidently the back niello mixture.  The etchings on the ball or lovely.  One is of an elephant, and the other I cannot identify.  It looks like a boat perhaps,
The candle holders are 5" tall with a 3-1/2" diameter base.
Excellent vintage condition.
