This Matilde Poulat style brooch has been repurposed into a pendant and features natural coral and turquoise cabochons.
The segmented brooch is in the style of Matl’s dove pieces and has turquoise and coral cabochons set in plain bezels. There are five dangles hanging from the bottom segment and each has a turquoise cab. 2.5″ x 2.5″ in size.
The necklace is coral tubes, approximately 4mm x 2mm in size. The strands are accented with 990 silver beads that match the style of the brooch. The piece finishes with a sterling hook and eye and sterling findings
I think this may be the work of Gustavo Martinez, but since the hallmark is mis-stamped, it is hard to tell.
