We are very pleased to offer this antique brooch by Kandell & Marcus NY. Kandell & Marcus are known for their cascading rhinestone, waterfall brooches. This brooch is an unusual Kandell & Marcus. It features gold tone base metal "coils" wrapped to create the main portion, and oval shape. These "coils" are then adorned with amethyst and blue topaz colored rhinestones. There is a very distinctive center stone on this brooch. It's incredible, but we don't know what it is. We are able to date this back to the early 20th century by using the hinge. It is accented with cascading metal. Cascading design is signature Kendell & Marcus NY. This is a rare and exquisite antique brooch.
