Made in India- silver, crystal, candlestick sconces

Hi there!!  I would appreciate any help you can offer with 2 wall sconces I came across 10 years ago, after the death of an elderly neighbor.  Unfortunately, I have no history on them and the only identifying information I can find is a sticker that says "Made in India".  I boxed them when I got them, because I thought they are possibly made of silver...it has a texture-look & is not smooth, reflective-type of metal.  The crystals are attached with a thin metal, one of which has rusted onto a crystal.  Each sconce has 2 candlestick holders that more predominantly show the texture of the metal.  The sconces are pretty heavy, probably 4-5 lbs. each and because of that, I've yet to hang them on a wall.  Each is approximately 15"L x 10"W x 4" in depth.  Any thoughts, ideas or suggestions are appreciated...thank you!!
