Fabulous vintage Art Deco silver / antique gold tone and royal lapis lazuli blue glass cabochon floral necklace by Max Neiger. This is such a delicate and detailed piece with many features and techniques of manufacture that suggest it is a Neiger piece. This dress clip is another example of this line of designs: www.etsy.com/uk/listing/1737662857
The necklace is in very good vintage condition, with some age-related wear where the silver tone plating is worn so that the brass / antique gold tone is visible underneath. This gives an attractive antique appearance on the front surface, and is only properly visible on the reverse of the three front panels.
The necklace has a length of about 18 inches, perhaps having been extended a couple of inches in the past using two short lengths of antique gold tone chain on either side of the clasp. This could be removed if desired.
