Vintage Fiona Abstract Art Porcelain Brooche and Earrings Set

Unique abstract art style handcrafted porcelain brooche and earrings set. The edges are plated in what appears to be 22K gold leaf (an internet search and gold testing kit was used to determine this...however, I am making no guarantee that this is 22K gold). The colors are gold, blue, white and red. All pieces are signed "Fiona" or "F". She is an artist based in Vancouver. Brooche: 2.5" x 2.5" Earrings: 1.5" x 1.5"
