This is such an amazing piece and it looks and feels like an Alfred Philippe piece for Trifari, but unmarked. Please be sure to enlarge the photos and you will get an idea of the intricate details of this design and construction.
The brooch is in the form of a delphinium flower bouquet with three flowers with rich blue round rhinestones and embedded clear sparkling rhinestones inset into the tops of the flowers, the base of the flowers and in the ribbon that holds all three flowers together. There is some minor wear to the gold plating, which is why I feel this is a vermeil piece, but please note that I have not tested it. This piece is a very SIGNIFICANT brooch with tons of glam and presence. The stones are all present.
There may be a few that are slightly darker, but nothing that has to be corrected as far as I can tell. Again, enlarge the photos for a very close-up look at this amazing piece. The brooch is 4 3/4" from top to bottom and 2" across. The item "HIGH END DESIGNER VINTAGE Cobalt Blue Rhinestone Philippe Style Bouquet Brooch" is in sale since Sunday, August 23, 2015.
