Mexican Silver With Smokey Glass/Stone

A wonderful Pre-48 signed Sterling Mexico.15 1/4 in. long and the drop is 2 1/4 in.from the widest point tall and just under 3in. across. 1 1/2 in. long from the center cabachon to the bottom of the dangle. It weighs approx. 2.5oz. This is a heavy base of sterling not light. I understand that some in this design are solid but this is a handmade piece with a barely raised repousse relief. The maestro has combined the technique of the raised relief with the silver pushed down next to the raised area to create a REAL BEAUTY! It has an interestingly raw character to the piece and the glass or quartz (???) has a brownish pink cast. I have seen only a couple others similar and they were always done in amethyst so this is UNIQUE! WOW! LOOK AT THAT NECKLACE!
