RARE ANTIQUE GEORGIAN/VICTORIAN SILVER GOLD PLATED SHAWL CLASP WITH 5 AMETHYSTS

Description

THIS IS AN EXTREMELY RARE ITEM ! I HAVE NEVER SEEN ANOTHER ONE OF THAT AGE . IT IS UNMARKED , BUT FOR A SMALL CRESCENT MARK IN ONE OF THE KNOBS OF THE CLIPS , WHICH MAKE ME THINK IT IS FRENCH , WHO USE DIMINUTIVE SILVER MARKS.
THE CHAINS ARE HEAVY AND WELL MADE , THERE ARE FIVE GORGEOUS AMETHYSTS : THREE CUSHION SHAPE 15mm x 12mm x 6mm THAT HAVE A DARKER HUE AND TWO DROP SHAPED 29mm x 10mm x 7mm ( the depth measurements are approximate ) THAT HAVE A LIGHTER HUE.
THE GOLD PLATING IS MISSING IN SOME PLACES ( LIKE ON THE CLIPS)  BUT DO NOT DISTRACT IN THE GENERAL APPEARANCE OF THE JEWEL.
IF YOU PUT THE THREE CUSHION AMETHYSTS IN A STRAIGHT ROW , THEY MEASURE 18cm . THE TWO CHAINS WITH THE PEAR SHAPED AMETHYSTS ARE 10cm AND 8cm.
PLEASE LOOK AT THE PICTURES FOR CONDITION.
I acid tested for silver and it did not turn green
